MAILGRAM RESPIRATOR USERS WARNING The National Institute for Occupational Safety and Health (NIOSH) advises workers to discontinue using the SurvivAir Mark I self-contained breathing apparatus until the units have been inspected by the manufacturer and all necessary repairs or replacements have been sede.
NIOSH has learned that the high pressure hose assembly installed by the manufacturer in some of these respirators is not the assembly originally tested and approved by NIOSH for this respirator.
In addition, reports from two fire departments indicate the following serious malfunctions have occurred recently during use:
1.
Bursting of the high pressure hose assembly (part no.
960627).
2.
Malfunction of the relief valve (part no. 912620).
3.
Malfunction of the 0-ring in the main line assembly (part no. 824193).
Any one of these failures would result in imediate loss o' 'tir supply to the user.
In response to a NIOSH request, SurvivAir has agreed to d.iscontinue sale and distribution of the respirators until all three problems are -
corrected. Nn NIOSH has detennined that the three problems have been corrected, you will be advised that the stop sales request has been with-drawn page 1 of 2
