The OSHA revision of its Respiratory Protection Standard does affect all of the emergency response community as well as any other personnel who wear respirators to better protect them from the inhalation hazards they face when doing thier jobs or assigned tasks.

Those Companies, Fire Departments and Ambulance Corps that value the safety, health and well-being of their personnel must make the effort to meet or exceed all of the requirements of this OSHA standard, which took effect in 1998.


Our work with other Physicians in the area is well documented. Custom Fit Plus and its employees have provided/currently provide fit testing services to Dr. Jorge Gardyn of IOMR, Dr. John Folan of Sound Medical and Dr. Raymond Basri of Health Safety Specialists. We also perform fit testing for Baseline Medical throughout Nassau County. 

CUSTOM FIT PLUS will do all that is necessary to ensure the proper protection of those personnel wearing respirators.
