Safety and Health (NIOSH) advises workers to discontinue using the SurvivAir Nark I self-contained breathing apparatus until the units have been inspected by the manufacturer and all necessary repairs or replacements have been 58de.
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. 'ursting of the high pressure hose assembly (part no.
960627).
Malfunction of the relief valve (part no. 912520).
3.
Nalfunction of the 0-ring in the main line assembly (part no. 824193).
Any one of these failures would result in inmediate loss of air supply to the user.
In response to a NIOSH request.
SurvivAir has agreed to discontinue sale and distribution of the respirators until all three problems are corrected.
Mhen NIOSH has determined that the three problems.have been corrected, you will be advised that the stop sales request has been with-drawn page 1 of'
