Last week I wrote about SCBA's being stored and used in low temperature environments and the special instructions that many manufacturers have developed (and require) the user to follow for such use. As usual, my article generated a lot of questions regarding SCBA's that are intended for "emergency use". So I thought it would be fitting to share my mental audit checklist I use when it comes to auditing a facility's emergency SCBA's. This may be old news to many, but based on the questions I have received some of this information may not be well known. All of these requirements can be found in 1910.134. I am sorry I am not able to do this for all countries, but keep in mind most industrialized nations have similar respirator requirements and if the country in which you are working does NOT, you should seriously consider implementing these OSHA requirements.
