Another operational objective is the quarantine of the area and protection of the of the response team. The Material Safety Data Sheet (MSDS) for the pellets indicates that burning releases toxic smoke. This indicates that the team needs to use air-purifying respirators (A.P.R) and supplied-air respirators (S.A.R). The toxic smoke in the area calls for a supplied air respirator approach. This is accomplished taking air from a secure container separate from the contaminated area through mask and tubing. Supplied-air respirators offer the highest level of protection against the smoke.
