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.

A Dosimeter for the Future: a History of the doseBadge

Sep 12, 2018

In 1995, a team of young engineers at Cirrus Research set to work on revolutionising the design and functionality of noise dosimeters. Their hard work and tireless dedication to the protection of people’s hearing led them to design the doseBadge, which has now become synonymous with personal noise exposure measurement. The process of designing the doseBadge wasn’t easy or without challenge, as the Cirrus engineers had to develop something that recorded all the necessary data, whilst ensuring that the person wearing the equipment wasn’t disturbed, and that the equipment itself complied with the Noise At Work regulations, in addition to being low cost, reliable, lightweight, tamper-proof and compliant with the acoustic standard. Some may have thought “why bother?”, but there was a recognition within the Cirrus team that dosimeters, at the time were very unreliable, cumbersome, liable to tampering and potentially dangerous, as the microphone cable could easily have been caught in heavy industrial machinery, causing serious injuries to those wearing them.

Those processes have changed (for the better) as we provide an OSHA and ISO-approved method for fit-testing. Our patented controlled negative pressure (CNP) technology lets you perform a simple fit test in only 3 minutes!
