Air Not Aerosol

Jun 5, 2019

Let’s talk about fit testing. Fit testing should identify a mask that best suits you, and this includes it being suitable for your job. When you go to fit test your mask, the most important part is walking away with the confidence that it will protect you against the respiratory hazards you face at work. This means you want the most rigorous, most protective, and most accurate means of fit testing your mask.

Massachusetts Public Workers Joining OSHA: Respiratory Safety Protections

Apr 15, 2019

Public workers are responsible for teaching our children, putting out fires, and protecting our streets. They do things daily that we may take for granted including cleaning our water, picking up our trash, and maintaining our roads. Despite all the work they do to keep our communities functioning, many public workers are not provided the same safety and health protections as those of us who work in the private sector. There is nothing that suggests any of the jobs public workers perform are any less dangerous than their private sector counterparts, and there is no reason to assume this labor force is receiving the same safety and health considerations without these protections in place. Labor advocacy groups have been fighting for years across the country to expand safety and health protections to cover public workers. Thus far, only 28 states extend Occupational Safety and Health Administration (OSHA) protections to their public employees. As of February 1st, 2019, the State of Massachusetts joined these states.

The Importance of Respiratory Protection at Every Fire and why FIT TESTING Matters.

Mar 11, 2019

The Alarm tones go off in the Fire Station about 2:45 pm – the voice says 3 and 1 dispatch (3 engines and 1 ladder) electrical fire in garden office complex. The firefighters head to the apparatus bay, jump in their turnout pants and boots that have been placed near the truck and head to the call lights and siren. When they arrive on scene, the initial report is that a construction company hit an electrical line nearby which resulted in a small explosion and a small fire in this garden office complex. The engineering system extinguished the fire as per design and fire code.

We work 12-hour shifts. What dosimeter criterion time should we use?

Feb 18, 2019

Is it just me, or can trying to decipher an OSHA regulation be confusing? Take, for instance, the OSHA Occupational Noise Exposure Standard (29 CFR 1910.95). The OSHA noise standard defines the action level to enroll an employee in a hearing conversation program as “an 8-hour time-weighted average of 85 decibels measured on the A-scale, slow response, or equivalently, a dose of 50 percent.” Because the action level is based on an exposure for an 8-hour work shift, a common point of confusion is what to do for work shifts that are not 8 hours, such as 10- or 12-hour work shifts. A common question we are asked is, “We work a 12-hour shift: Should I use 8 or 12 as the time duration on my noise dosimeter to calculate the time-weighted average?” Understanding how changing the time duration of a noise dosimeter sample affects the results, and how this relates to the noise standard, will help us make the best decision.
