Depending on how and where asbestos was applied, it may not pose a risk to most users of the building. If the fibers are not dislodged, they cannot become airborne or be inhaled and thus the risk is absent.

The intent of this procedure is to gain access and assess ceiling spaces where encapsulated fire spray has been used on structural steel beams. In such areas the following procedures shall be taken:

Prior to the start of the work the Facilities management supervisor shall be notified of:

  • The name of the worker performing work,
  • The dates and the time of the work and,
  • The location and type of the work to be conducted.
    The following Personal Protective Equipment (PPE) shall be used:
  • Use of respiratory protection is not required however if a worker requests to wear a respirator it shall be (at minimum) a half-faced air purifying respirator with N-100, R- 100 or P-100 particulate (HEPA) filters,
  • Use of protective clothing is not required however if a worker requests to wear protective clothing it shall be (at minimum) a disposable suit (Tyvek® or equivalent) with a hood,
  • Protective gloves and,
  • Safety glasses with side shields and safety shoes/boots.
Procedure:
  • Eating, drinking, chewing gum or smoking is not permitted in the work area.
  • Refer to asbestos report to determine location and general condition of asbestos fire spray.
  • If fire spray and other asbestos are reported in good condition, work may proceed. If condition of asbestos is reported as damaged, workers must use Type 2 procedures (Refer to Appendix D).
  • Ensure work is done during times of low or no occupancy in affected areas.
  • Don protective clothing and respiratory protection (half face air purifying respiratory with N, R or P-100 HEPA filters) if worker requests this PPE.
  • Carefully remove a ceiling tile that is located at least 2 meters (6.5 feet) away from fire sprayed beams.
  • Using a flashlight, carefully inspect the area where work will be done.
  • Ensure fire spray is fully encapsulated, is in good condition and is not damaged.
  • Ensure there is no asbestos debris in the area to be worked on.
  • If asbestos debris is found, do not disturb, clean-up, cover, move or touch material. Carefully replace the ceiling tile and notify supervisor or proceed using Type 2 precautions (Refer to Appendix D).
  • If no debris or damage is present, assigned work may proceed, provided the working distance from asbestos containing material (ACM) is equal to or greater than an arm’s length plus the length of any tools/equipment required for the job, and the work will not disturb asbestos.
  • Complete work in the ceiling space without disturbing asbestos.
  • Reinstall ceiling tile(s).
