• Personnel in structural firefighting PPE entering an incident where the presence of hazardous materials was unknown and contamination occurs
• Damage to chemical protective clothing (CPC) causing an opening or tear in the level of protection
• Failure or malfunction of self-contained breathing apparatus (SCBA)
• Injury or ill health of a member of personnel
In these situations, using a decontamination shower structure or other designed approach for decontamination may either be too time-consuming or unsuitable as it may exacerbate the problem (possibly by forcing a contaminant through a damaged suit).
