Question 1:   What does asbestos look like?

Asbestos cannot always be identified by appearance alone. Many building materials may contain asbestos without visible signs. Proper sampling and laboratory testing are required to confirm asbestos content.

Question 2:  Is asbestos dangerous if untouched?

Asbestos-containing materials are generally lower risk when they are intact and undisturbed. The risk increases when materials become damaged, deteriorated, cut, drilled, sanded, or disturbed during renovation or demolition activities.

Question 3:   When is asbestos testing required?

Testing is recommended before renovation, demolition, drilling, cutting, sanding, or disturbing suspect building materials, especially in older buildings. 

Question 4:  What is air clearance testing?

Air clearance testing is performed after asbestos removal procedures to help verify that airborne fiber levels meet acceptable clearance requirements before containment removal or re-occupancy.

Question 5:  What is a high-risk asbestos job?

High-risk asbestos work may involve large-scale removal, spray-applied asbestos, major disturbance of asbestos-containing materials, or activities with increased potential for airborne fiber release. These projects typically require full containment, decontamination facilities, negative air systems, and strict procedures.

Question 6:  Can occupants stay in the building during asbestos removal?

This depends on the scope of work, containment methods, building conditions, and regulatory requirements. In some situations, occupants may remain in unaffected areas. In other cases, temporary relocation may be recommended or required for safety reasons.

Question 7:  What is negative air pressure?

Negative air pressure is created using HEPA-filtered negative air machines to help prevent airborne fibers from escaping the containment area into surrounding spaces.

Question 8:  What PPE is required for asbestos work?

Depending on the risk level and scope of work, PPE may include respirators, disposable protective suits, gloves, eye protection, and decontamination procedures. PPE requirements must comply with applicable regulations and exposure control procedures.

Question 9:  What is an Exposure Control Plan (ECP)?

An Exposure Control Plan is a documented safety procedure outlining hazard controls, PPE requirements, work methods, decontamination procedures, emergency procedures, and exposure reduction measures for asbestos-related work.

Question 10:  What is the difference between low-risk, moderate-risk, and high-risk asbestos work?

Risk levels are determined by the type of material, condition of the asbestos-containing material, and the likelihood of airborne fiber release. Higher-risk activities require stricter containment, PPE, monitoring, and decontamination procedures.

Question 11:  Why is air monitoring important during asbestos work?

Air monitoring helps evaluate airborne fiber concentrations, confirm the effectiveness of containment and controls, and support worker and occupant safety during asbestos-related activities.

Question 12:  How is asbestos waste disposed of?

Asbestos waste must be properly sealed, labeled, transported, and disposed of according to hazardous material handling requirements and approved disposal procedures.

Question 13:  Are asbestos fibers visible in the air?

No. Asbestos fibers are microscopic and cannot typically be seen without specialized laboratory analysis equipment.

Question 14:  What should I do if I suspect asbestos in my property?

Avoid disturbing the material and contact qualified professionals for inspection, testing, and guidance before starting renovation or demolition work.
