Questions Asked in Asbestos Personal Protective Equipment (PPE) Use Interview
Q 1. What are the key components of a complete Asbestos PPE ensemble?
A complete Asbestos PPE ensemble is crucial for protecting workers from asbestos fibers. It’s not just about one piece of equipment; it’s a system designed to minimize exposure at every point. Think of it like a suit of armor, each piece vital for complete protection.
- Respirator: This is the most critical component, specifically an air-purifying respirator with a HEPA (High-Efficiency Particulate Air) filter capable of filtering out asbestos fibers. The type of respirator will depend on the asbestos concentration and work being done.
- Tyvek Suit or Coverall: A disposable, non-permeable suit that prevents asbestos fibers from contacting the skin. It should be completely sealed to prevent fiber penetration.
- Gloves: Durable, nitrile gloves are generally preferred, providing a good barrier against asbestos contamination. They should be worn over the suit cuffs for full coverage.
- Hood or Hard Hat: Protects the head and neck area. A hood is usually preferred as it seals better with the suit.
- Boot Covers: Protect footwear from contamination and prevent the tracking of asbestos fibers.
- Goggles or Face Shield: Eye protection is essential to prevent asbestos fibers from entering the eyes.
Remember, proper fit and maintenance of each component are paramount to the effectiveness of the entire ensemble.
Q 2. Describe the proper donning and doffing procedures for an asbestos respirator.
Donning and doffing (putting on and taking off) a respirator requires meticulous attention to detail to avoid contaminating the respirator or oneself. Think of it like a surgical procedure – every step counts.
Donning:
- Wash and dry your hands thoroughly.
- Inspect the respirator for any damage.
- Carefully place the respirator on your face, ensuring a proper seal around your nose and mouth.
- Adjust the straps for a snug, comfortable fit.
- Conduct a fit check (see Question 7 for details).
Doffing:
- Remove the respirator in a designated clean area.
- Avoid touching the outside of the respirator.
- Carefully remove the straps without touching the filter.
- Dispose of the respirator in a designated container according to regulations.
- Wash your hands thoroughly.
Improper donning and doffing can significantly reduce the effectiveness of the respirator and increase the risk of asbestos exposure.
Q 3. Explain the different types of respirators used in asbestos abatement and their limitations.
Several respirator types are used in asbestos abatement, each with its own strengths and limitations. The choice depends on the asbestos concentration level.
- HEPA Filter Respirators (Air-Purifying Respirators): These are the most common type used in asbestos abatement. They remove asbestos fibers from the air you breathe. Limitations include the need for proper fit and regular filter replacement; they won’t protect against oxygen-deficient environments.
- Supplied-Air Respirators (SARs): These provide a continuous supply of clean air from an external source, offering superior protection in high-concentration environments. Limitations include the need for a compressed air source and the potential for equipment malfunctions.
- Powered Air-Purifying Respirators (PAPRs): PAPRs use a battery-powered fan to force air through a HEPA filter. They offer better comfort and lower breathing resistance compared to traditional HEPA respirators. However, they are more expensive and require battery maintenance.
It’s crucial to remember that all respirators have limitations. No respirator can guarantee 100% protection. Proper training, proper respirator selection, and adherence to safety procedures are essential for minimizing risk.
Q 4. What are the legal requirements for providing and maintaining Asbestos PPE?
Legal requirements for Asbestos PPE vary by jurisdiction but generally mandate that employers provide, maintain, and ensure proper use of appropriate PPE for asbestos work. This is mandated by OSHA (Occupational Safety and Health Administration) in the United States and equivalent agencies in other countries.
Key requirements often include:
- Providing appropriate PPE: Employers must provide respirators, coveralls, gloves, eye protection, and other necessary PPE based on the task and asbestos concentration.
- Fit testing respirators: Regular fit testing is required to ensure a proper seal and respirator effectiveness.
- Training and education: Employees must receive training on the proper use, donning, doffing, and maintenance of PPE.

Q 6. What are the limitations of disposable versus reusable respirators in asbestos work?
Disposable and reusable respirators both have their place in asbestos work, but their limitations differ significantly.
- Disposable Respirators: Offer convenience and eliminate the need for cleaning and maintenance. However, they are more expensive in the long run and generate more waste. They are generally preferred for situations with high asbestos concentrations where thorough protection is required.
- Reusable Respirators: More cost-effective in the long term but require cleaning, maintenance, and regular fit testing. They are suitable for lower-concentration situations and regular maintenance allows for continued use.
The best choice depends on the specific application, frequency of use, budget, and available resources. Always follow manufacturer recommendations and regulatory guidelines for proper respirator selection.
Q 7. Explain the importance of fit testing for respirators in asbestos abatement.
Fit testing is crucial for ensuring a proper seal between the respirator and the worker’s face. A poorly fitting respirator allows asbestos fibers to bypass the filter, negating its protective effect. Think of it like a poorly fitting helmet – it won’t offer sufficient protection.
Several methods exist for fit testing, including:
- Qualitative Fit Test (QLFT): Involves performing specific maneuvers (e.g., head movements, deep breaths) while wearing the respirator and detecting any leaks by smell or taste of a test agent.
- Quantitative Fit Test (QNFT): Uses instrumentation to measure the amount of leakage of a test agent into the respirator. This is a more precise method.
Regular fit testing, often required annually or after any significant facial changes, is non-negotiable to maintain worker safety in asbestos abatement. Failure to do so can have serious consequences.
Q 8. How would you address a PPE malfunction during an asbestos removal operation?
A PPE malfunction during asbestos removal is a serious safety incident. Immediate action is crucial. First, the affected worker must immediately leave the contaminated area. Any compromised PPE, such as a torn respirator or damaged suit, must be removed and replaced with new, uncompromised PPE. The supervisor should be immediately notified. The malfunction itself needs to be documented – what failed, when it failed, and the circumstances. Depending on the severity (e.g., a small tear versus a complete respirator failure), the contaminated area may need to be evacuated and decontaminated before work resumes. A thorough investigation should follow to determine the cause of the malfunction and prevent recurrence, such as implementing stricter inspection protocols or replacing faulty equipment. This might involve reviewing training procedures to ensure workers understand proper PPE inspection and donning techniques. Imagine a scenario where a worker’s respirator malfunctions mid-abatement; immediate action prevents potential exposure. This highlights the importance of having readily available backup PPE and a well-defined emergency response plan.
Q 9. What are the specific PPE requirements for different asbestos abatement activities (e.g., demolition, encapsulation)?
PPE requirements vary depending on the asbestos abatement activity. For demolition, which involves the physical breaking down of asbestos-containing materials, the highest level of protection is needed. This typically includes a fully encapsulated, vapor-resistant suit, a self-contained breathing apparatus (SCBA), gloves, boots, and eye protection. Encapsulation, which involves sealing asbestos in place, typically requires less stringent PPE. While a respirator is always necessary to prevent inhalation of airborne fibers, a less robust suit and gloves may suffice, depending on the specific job tasks and potential for fiber release. Repair and maintenance tasks may call for a variety of PPE, depending on the risk level. The key is a risk assessment that dictates the appropriate level of protection, always erring on the side of caution. For example, removing asbestos-containing floor tiles (demolition) necessitates a full SCBA, whereas sealing minor cracks in asbestos cement pipe (encapsulation) may allow for the use of an air-purifying respirator, provided air quality monitoring demonstrates it is safe to do so. All activities necessitate thorough training and adherence to the selected PPE protocols.
Q 10. How do you manage and dispose of contaminated PPE after an asbestos job?
Contaminated PPE is considered hazardous waste and requires careful management and disposal. After an asbestos job, all used PPE must be carefully removed and placed into designated, leak-proof containers. These containers are usually double-bagged to prevent leakage and labeled clearly with the appropriate hazard warnings. The bags must then be sealed and transported to an approved hazardous waste disposal facility that is licensed to handle asbestos waste. It’s crucial that the disposal process strictly adheres to all local, state, and federal regulations to minimize environmental risks and comply with relevant safety standards. For example, each container might include a waste manifest detailing the contents and the disposal site. This methodical process ensures that the hazardous material is contained and disposed of properly, thus protecting the environment and public health.
Q 11. What are the OSHA regulations regarding Asbestos PPE?
OSHA regulations regarding asbestos PPE are stringent. OSHA’s 29 CFR 1926 Subpart N, specifically 1926.1101, outlines the requirements for asbestos abatement. This covers the selection, use, and maintenance of all necessary PPE, including respirators, protective clothing, and eye protection. The regulations are designed to minimize employee exposure to asbestos fibers and prevent asbestos-related illnesses. OSHA mandates that employers conduct regular inspections of the PPE, ensure it is properly maintained, and provide adequate training for workers on the correct use and limitations of the equipment. Employers must also follow a written respiratory protection program conforming to 29 CFR 1910.134. Failure to comply with these regulations can result in significant penalties and legal action. The specifics of the required PPE will depend on the specific tasks being performed and the potential for asbestos exposure.
Q 12. What are the signs and symptoms of asbestos-related illnesses?
Asbestos-related illnesses can have a long latency period, meaning symptoms may not appear for decades after exposure. The most common asbestos-related diseases include asbestosis (lung scarring), lung cancer, and mesothelioma (cancer of the lining of the lungs or abdomen). Symptoms of asbestosis may include shortness of breath, persistent cough, and chest tightness. Lung cancer symptoms are similar to those of other lung cancers, including coughing up blood, chest pain, and unexplained weight loss. Mesothelioma is often diagnosed at a late stage and carries a poor prognosis. It frequently presents with chest pain, shortness of breath, and abdominal pain. It is important to note that not everyone exposed to asbestos will develop these illnesses. However, any exposure to asbestos, no matter how minimal, carries some degree of risk. Regular health screenings and monitoring are vital for individuals with a history of asbestos exposure.
Q 13. Describe the proper decontamination procedure for workers and equipment after asbestos exposure.
Decontamination is crucial for preventing the spread of asbestos fibers after exposure. For workers, this involves a multi-step process. First, all contaminated PPE must be removed in a designated decontamination area, placed in a designated container, and disposed of according to regulations. Next, workers should thoroughly shower using soap and water, and they should remove any contaminated clothing inside a shower enclosure. The shower water is collected and treated as hazardous waste. After showering, the workers should change into clean clothing. The decontamination area is typically self-contained and equipped with a ventilation system to prevent airborne fiber contamination. For equipment decontamination, similar principles apply. Equipment is thoroughly cleaned using appropriate methods and cleaning agents, with all wastewater treated as hazardous waste. All equipment is then checked to ensure the cleanliness. The process ensures that no residual asbestos fibers remain to contaminate workers or the environment.
Q 14. How do you ensure compliance with all relevant health and safety regulations regarding PPE?
Compliance with health and safety regulations regarding PPE is paramount. This involves a multi-faceted approach. Firstly, a comprehensive risk assessment must be conducted before any asbestos work commences to determine the necessary PPE requirements. Employers should provide adequate training to all workers on the correct selection, use, inspection, and maintenance of PPE. Regular monitoring and inspection of PPE are crucial. This includes checking for damage and wear and ensuring that it’s fit for purpose. Proper record-keeping is also necessary, documenting training, inspections, and any incidents or malfunctions. Finally, regular audits and compliance checks must be conducted to ensure continuous adherence to all relevant standards and regulations. A robust safety culture, fostered through leadership engagement and worker empowerment, is key to ensuring compliance. For instance, regular toolbox talks should remind workers about the importance of PPE and their rights to a safe workplace.

Refusal to wear mandated PPE is a serious safety violation. The approach should be a progressive one, emphasizing education and collaboration, while maintaining a firm stance on safety. Here’s how I’d handle such a situation:
- Initial Discussion: I would privately speak with the worker to understand the reason for their refusal. Is there a discomfort issue with the PPE? Are they lacking proper training or understanding of the risks? Addressing the root cause is essential.
- Re-training and Education: If the refusal stems from a lack of understanding, I would provide additional training, focusing on the specific hazards of asbestos exposure and the vital role of PPE in mitigating those risks. I might even use visual aids, videos, or case studies to illustrate the consequences of non-compliance.
- PPE Fit and Comfort: Sometimes, discomfort with the PPE is the issue. I’d ensure the worker is using correctly fitted PPE. If necessary, I’d arrange for a proper fit test for respirators or provide alternative PPE options that are both effective and comfortable.
- Disciplinary Action: If the refusal persists after attempts at education and accommodation, disciplinary action may be necessary, in accordance with company policy and potentially, legal requirements. This could range from verbal warnings and written reprimands to suspension or termination, depending on the severity and frequency of the violation.
- Documentation: Throughout the process, meticulous documentation is crucial. This includes records of conversations, training sessions, and any disciplinary actions taken.
The key is to balance safety with a fair and understanding approach. The goal is to ensure worker safety and compliance, not to punish the worker.
Q 17. How do you select the appropriate PPE for a specific asbestos project?
Selecting the right PPE for an asbestos project is a critical step in ensuring worker safety and compliance with regulations. It involves careful consideration of several factors:
- Type of Asbestos Work: The level of asbestos exposure varies depending on the task. Demolition will involve much higher airborne fiber concentrations than inspections, requiring different levels of protection.
- Airborne Fiber Concentration: Measurements of asbestos fiber concentrations (ideally taken by a qualified industrial hygienist) help in determining the required level of respiratory protection. Higher concentrations necessitate more robust respirators.
- Work Environment: The work environment can influence PPE choices. Hot, humid conditions might necessitate lighter-weight PPE, but it must still provide adequate protection. The presence of sharp objects might influence glove selection.
- Regulatory Requirements: Regulations, such as OSHA standards, dictate minimum PPE requirements based on the type of asbestos work. These regulations must be followed to ensure compliance.
Example: During asbestos abatement, workers may require a combination of a supplied-air respirator (SAR) or a high-efficiency particulate air (HEPA) filter respirator, a fully encapsulating protective suit, gloves, eye protection, and boots. This contrasts with asbestos inspection, where a HEPA filter respirator may suffice with a protective suit and appropriate gloves and eye protection.
PPE selection isn’t just about choosing individual items; it’s about choosing a complete system designed to provide comprehensive protection against all identified hazards. Proper training on how to use and maintain this system is essential.
Q 18. What are the differences between air-purifying respirators and supplied-air respirators?
Both air-purifying respirators (APRs) and supplied-air respirators (SARs) are used to protect workers from inhaling asbestos fibers, but they differ significantly in how they achieve this:
- Air-Purifying Respirators (APRs): These respirators filter the air the worker breathes. They rely on filters to remove airborne contaminants, including asbestos fibers. The air is drawn into the respirator through the filter and then into the worker’s lungs. APRs are effective for lower concentrations of asbestos fibers, but their effectiveness depends on the quality of the filters and their proper maintenance.
- Supplied-Air Respirators (SARs): SARs provide a continuous supply of clean air from an independent source, either a compressed air tank or an air-purification system. This means the worker is breathing air that is completely uncontaminated by asbestos fibers. SARs offer greater protection than APRs, especially in environments with high concentrations of asbestos fibers.
Key Differences Summarized:
- Air Source: APRs filter ambient air; SARs provide a separate supply of clean air.
- Protection Level: SARs generally offer higher protection than APRs, especially in high-concentration environments.
- Limitations: APRs can be limited by filter capacity and potential breakthrough; SARs offer a more reliable and consistent level of protection.
- Maintenance: APRs require regular filter changes; SARs require maintenance of the air supply system.
The choice between an APR and a SAR depends on the specific asbestos project and the level of asbestos concentration. A qualified industrial hygienist should determine the appropriate respirator type.
Q 19. Describe the role of a supervisor in ensuring proper PPE use by workers.
The supervisor plays a vital role in ensuring proper PPE use by workers. Their responsibilities extend beyond simply issuing PPE; they’re critical in fostering a safety-conscious environment.
- Pre-Job Briefing: Supervisors must conduct thorough pre-job briefings to review the specific hazards, the required PPE, and the proper procedures for its use and maintenance. This includes checking if workers are comfortable with the PPE and if any adjustments are needed.
- PPE Inspection: Supervisors should regularly inspect workers’ PPE to ensure it’s in good condition and properly worn. This includes checking for damage, proper fit, and appropriate use.
- Training Reinforcement: Supervisors must reinforce training on PPE use and ensure workers understand the importance of wearing PPE correctly and consistently. They are the first line of defense in ensuring that training is understood and applied.
- Enforcement of Rules: Supervisors have the responsibility to enforce company policies and regulatory requirements regarding PPE use. They must address any violations promptly and consistently, ensuring a safe work environment.
- Example Setting: Supervisors must lead by example, always wearing the appropriate PPE when working in asbestos-contaminated areas. Their actions speak volumes and inspire workers to follow suit.
- Incident Reporting: Supervisors must ensure that any accidents or near misses related to PPE failure are promptly reported and investigated.
Effective supervision is crucial for preventing accidents and protecting workers from the dangers of asbestos exposure.
Q 20. What are the procedures for reporting accidents or injuries related to PPE failure?
Reporting accidents or injuries related to PPE failure is critical for several reasons: preventing future incidents, ensuring worker safety, and fulfilling regulatory requirements. The process typically involves several steps:
- Immediate Action: First aid should be administered if necessary. The area should be secured to prevent further exposure or injury.
- Incident Report: A detailed incident report must be filed, including the date, time, location, description of the incident, names of involved personnel, type of PPE involved, any observed PPE failures (e.g., cracks in the suit, respirator malfunction), injuries sustained, and any corrective actions taken.
- Investigation: A thorough investigation should be conducted to determine the root cause of the incident. This might involve interviewing witnesses, examining the PPE, reviewing safety procedures, and analyzing the work environment.
- Corrective Actions: Based on the investigation, corrective actions should be implemented to prevent similar incidents from happening again. This might include changes to safety procedures, improved training, replacement of faulty PPE, or adjustments to work practices.

- Documentation: All aspects of the incident, investigation, and corrective actions should be meticulously documented.
A well-defined incident reporting system is essential for continuous improvement in workplace safety.
Q 21. What are the common hazards associated with asbestos work and how does PPE mitigate these hazards?
Asbestos work presents several significant hazards, all of which can be mitigated to a great extent through the proper use of PPE.
- Inhalation of Asbestos Fibers: This is the most serious hazard. Asbestos fibers, when inhaled, can cause various respiratory diseases, including asbestosis, lung cancer, and mesothelioma. Mitigation: Respiratory protection (APRs or SARs) is critical to prevent fiber inhalation. The respirator must be properly fitted, maintained, and worn consistently throughout the duration of exposure.
- Skin Contact: Asbestos fibers can cause skin irritation or even more serious skin problems. Mitigation: Protective suits, gloves, and other protective clothing prevent skin contact with asbestos fibers.
- Eye Irritation: Asbestos fibers can irritate the eyes. Mitigation: Eye protection, such as safety goggles or face shields, is essential to prevent this.
- Ingestion: Ingesting asbestos fibers is possible and can also cause health problems. Mitigation: Protective clothing, careful hygiene practices (hand washing), and avoiding eating or drinking in contaminated areas mitigate this risk.
PPE is not a complete solution on its own. It must be used in conjunction with safe work practices, proper engineering controls (like containment), and good hygiene to create a comprehensive safety program. It’s vital to remember that even with perfect PPE usage, some residual risk remains and minimizing exposure is paramount.
Q 22. Explain the importance of regular PPE inspections and maintenance.
Regular inspection and maintenance of Asbestos Personal Protective Equipment (PPE) is paramount to ensuring its effectiveness and the safety of workers. A damaged or improperly maintained respirator, for example, could fail to filter asbestos fibers, directly exposing the wearer to harmful airborne particles.
- Visual Inspections: Daily checks are crucial. Look for rips, tears, holes, or any signs of wear and tear in suits, gloves, and boots. Check respirators for proper seals, damaged filters, or loose straps.
- Functional Testing: Regularly test respirators for proper fit and function using qualitative fit tests (QLFTs) or quantitative fit tests (QNFTs) as required. These tests verify the respirator’s ability to create a proper seal against the wearer’s face.
- Cleaning and Decontamination: PPE must be cleaned and decontaminated properly after each use, following specific protocols to avoid cross-contamination. This often involves specialized cleaning solutions and procedures.
- Repair and Replacement: Damaged PPE should be immediately repaired (if possible and according to manufacturer guidelines) or replaced. Never compromise on the integrity of your safety gear.
- Record Keeping: Maintain detailed records of all inspections, maintenance, and replacements. This documentation is crucial for compliance and demonstrating due diligence.
Think of it like this: You wouldn’t drive a car with worn-out brakes; similarly, you shouldn’t work with asbestos using compromised PPE.
Q 23. How do you ensure all workers understand and comply with PPE protocols?
Ensuring worker understanding and compliance with PPE protocols requires a multi-pronged approach that combines training, reinforcement, and accountability.
- Comprehensive Training: Before any asbestos work begins, workers must receive thorough training on the risks of asbestos exposure, the proper selection and use of appropriate PPE, and the importance of following established procedures.
- Hands-on Practice: Training should include hands-on practice sessions where workers can learn to correctly don and doff (put on and take off) their PPE. This is particularly critical for respirators, where a proper seal is essential.
- Regular Refresher Training: Regular refresher courses help reinforce best practices and address any changes in regulations or procedures.
- Observation and Monitoring: Supervisors should regularly monitor workers to ensure they are correctly using PPE. This includes observing proper donning and doffing procedures and checking for any PPE malfunctions.
- Clear Communication and Accountability: Establish clear communication channels to allow workers to report any PPE issues or concerns without fear of reprisal. Implement consequences for non-compliance to demonstrate the seriousness of the protocols.
Example: A company might use a buddy system where experienced workers mentor new employees and oversee their PPE use.
Q 24. What are the considerations when selecting PPE for workers with pre-existing medical conditions?
Selecting PPE for workers with pre-existing medical conditions requires careful consideration to ensure both their safety and their comfort. Certain conditions may limit the type of PPE a worker can safely use.
- Respiratory Conditions: Workers with asthma, emphysema, or other respiratory problems might have limitations on the types of respirators they can use. A medical evaluation by a physician is often necessary to determine respirator suitability and appropriate fit testing.
- Skin Conditions: Workers with sensitive skin or allergies might require specialized gloves or other protective clothing to prevent irritation or allergic reactions.
- Cardiac Conditions: Workers with heart conditions may be limited in their ability to handle strenuous physical activity in full PPE. Work tasks should be tailored to their capabilities.
- Consultation with Healthcare Professionals: Always consult with occupational health professionals and the worker’s physician to determine appropriate PPE and any necessary accommodations. This collaborative approach ensures the worker’s safety and comfort.
For instance, a worker with a known allergy to latex would require non-latex gloves.
Q 25. Describe the role of air monitoring in determining the appropriate level of PPE.
Air monitoring plays a crucial role in determining the appropriate level of PPE required for asbestos abatement. By measuring the concentration of asbestos fibers in the air, we can assess the level of risk and select the most suitable PPE.
- Air Sampling: Air samples are collected before, during, and after abatement activities to determine the concentration of asbestos fibers in the air. This is done using specialized air sampling pumps and filters.
- Fiber Counting: The collected samples are sent to a certified laboratory for fiber counting using phase contrast microscopy (PCM). This determines the concentration of asbestos fibers per cubic centimeter of air.
- Risk Assessment: The results of the air monitoring are used to assess the risk level of asbestos exposure. Higher fiber counts necessitate the use of more protective PPE.
- PPE Selection: Based on the risk assessment, appropriate PPE, including respirators with specific filtration capabilities (e.g., HEPA filters), protective suits, gloves, and boots, are selected.
If air monitoring reveals high levels of asbestos fibers, a higher level of respiratory protection, such as a powered air-purifying respirator (PAPR), might be required. Conversely, if levels are low, a half-mask respirator might suffice.
Q 26. Explain the importance of proper record-keeping regarding PPE use and maintenance.
Proper record-keeping regarding PPE use and maintenance is crucial for ensuring worker safety, regulatory compliance, and demonstrating due diligence.

These records are vital for audits, investigations, and demonstrating compliance with relevant safety regulations. Imagine a situation where a worker claims they were not properly trained; complete and accurate records provide critical evidence.
Q 27. How would you explain the importance of PPE to a new employee?
Explaining the importance of PPE to a new employee requires a clear, concise, and relatable approach. Focus on the ‘why’ behind the PPE, not just the ‘how’.
“Welcome to the team! We work with asbestos, a material that contains microscopic fibers invisible to the naked eye. These fibers can cause serious lung diseases if inhaled. Your personal protective equipment (PPE) is your best defense against these risks. Think of it as your suit of armor protecting you on the job. It’s essential that you always wear it correctly according to the training you receive. We’ll provide comprehensive training on how to use all the PPE elements, and we’ll always be here to answer your questions.”
I would then show them the PPE, explain each piece’s function, and demonstrate proper donning and doffing procedures. I’d emphasize that wearing PPE is not just a rule, but a crucial element of their safety and well-being.
Q 28. What are the potential consequences of failing to use proper PPE in asbestos abatement?
Failing to use proper PPE during asbestos abatement can lead to severe and potentially fatal consequences.
- Asbestosis: This is a chronic lung disease caused by inhaling asbestos fibers. Symptoms include shortness of breath, coughing, and chest pain. It can be debilitating and ultimately fatal.
