Earlier this year, I wrote an article titled “What type of respirator do I need?” in which I explained how respirator users and administrators can use data to determine the proper type of respiratory protection that would be needed. But this article was written under the assumption that the user/administrator had the most essential piece…...

The NIOSH Respirator Selection Logic (RSL) relies entirely on whether the airborne concentration of a contaminant exceeds a defined exposure limit (such as the NIOSH Recommended Exposure Limit [REL] or OSHA Permissible Exposure Limit [PEL]), regardless of what the chemical’s vapor pressure is. However, vapor pressure plays a decisive role in selecting a respirator, particularly…...
Assigned Protection Factors (APF), a new guidance document published by OSHA provides employers with vital information for selecting respirators for employees exposed to contaminants in the air. OSHA revised its Respiratory Protection standard in 2006 to add APFs and Maximum Use Concentration (MUC) provisions. APF means the workplace level of respiratory protection that a respirator or…...

Simply stated… We inhale the exact same proportion of oxygen at high altitude as you do at sea level, but because the gas is at a lower pressure, the oxygen molecules are not pushed into our bloodstream with enough force to adequately oxygenate your tissue. Whether you are at sea level or standing on the…...
One of the most common questions I used to get on emergency response scenes is: “How do you determine when we can stop wearing SCBAs and begin wearing Air Purifying Respirators”? The decision is often a heated debate due to the user’s lack of knowledge. The scary part is that these are trained HAZMAT Technicians…...

Does OSHA require an “individual” be appointed as the “respiratory protection program administrator,” or can the written respirator program state the “safety department,” “EHS Department,” or “safety team members” are the program administrator?… Membership Required You must be a member to access this content.View Membership LevelsAlready a member?

MultiVapor is a computer tool for estimating breakthrough times and service lives of air-purifying respirator cartridges manufactured to remove toxic organic vapors from breathed air. It can also be used for larger filters and for carbon beds of any size prepared for laboratory studies. MultiVapor replaces the program, Breakthrough, which performs the same function for…...
A fundamental requirement of using respirators is NO facial hair that could interfere with the respirator’s operation or the respirator’s fit. OSHA states: 1910.134(g)(1)(i) The employer shall not permit respirators with tight-fitting facepieces to be worn by employees who have: 1910.134(g)(1)(i)(A) Facial hair that comes between the sealing surface of the facepiece and the face…...
Does your workplace use the handi-wipes for cleaning respirators? Do you feel this is compliant? After all it is a very common practice and how could it be so widely used if it is not compliant?????… Membership Required You must be a member to access this content.View Membership LevelsAlready a member?
