... asbestos is a danger to your employees
Last month we introduced the proposed changes in the asbestos regula-
tions and briefly outlined some of the standards your shop must meet to obey them This month we will take a closer look at some of the specific standards affecting your business show how much danger is involved in handling
asbestos and present some of the solu-
tions parts and equipment manufacturers have developed
When the 1974 asbestos inhalation
law went into effect most of the concern was for those employees involved in milling fabrication and construction A dust collection system designed for use with Ammco Tools Inc.'s brake shoe grinders Model 8925 efficiently collects contains and disposes of asbestos dust ground off brake shoes according to the company No external power source is required as a built suction fan pulls dust from the surface of the brake shoe and deposits it in a sealable disposable plastic bag Once installed the brake shoe grinder is said to meet or exceed Federal Clean Air Standards set by the OSHA Act of 1970

tons of asbestos consumed in the
United States in 1972 approximately
77 was used in the construction in-
dustry However further statistics reveal
that only 500,000 workers are exposed to asbestos in mining milling fabrication and construction Compare that number with the nearly one million American workers exposed to asbestos
while installing and maintaining clutch and brake linings A smaller per-
centage of the total asbestos is con-
sumed but a larger percentage of Amenca's work force is exposed
But how serious is the exposure A 1975 study done by Dr. W.J. Nicholson of Mt. Sinai Hospital detailed in a paper entitled Asbestos Exposure During Brake Lining Maintenance and Repair reveals some interesting statistics
Before studies were undertaken it was thought that the heat involved during the use of brakes caused a chemical breakdown transforming the asbestos in the linings into a relatively harmless dust The data presented in the paper indicates that workers engaged in car and truck brake service are exposed to
potentially hazardous levels of airborne
asbestos dust

A free call to OSHA's Chicago office revealed that the industrial hygiene inspectors will look favorably on indications of voluntary compliance The Chicago office is quite willing to answer any questions on this and any other OSHA regulations The free number is 1-800-621-0523
The National Institute for Occupational Safety and Health has suggested the following procedures for asbestos brake and clutch servicing in order to
reduce exposures
If possible an area should be des-
ignated for all brake and clutch repairs Entrances should be posted with warn
"
ing sign saying Asbestos dust hazard Avoid breathing dust Wear assigned protective equipment Do not remain in area unless your work requires it Breathing asbestos dust may cause asbes-
tosis and cancer
@ During brake servicing an air purifying respirator either single use or with replaceable particulate filter as approved by the Mining Enforcement and Safety Administration of NIOSH will be worn during all procedures starting with the removal of the wheels and including reassembly Such a respirator should also be worn during all clutch procedures from removal to installation
Model 1250 brake assembly washer intro-
duced by Ammco permits solvent washing of
brake assemblies and eliminates the prac-
tice of blasting asbestos particles and dust around the shop The specially designed gun which requires shop air pressure delivers a properly atomized stream of solvent without misting or waste The solvent returns to the sump through the perforated parts pan for recirculation As
parts are removed from the brake assembly
they are allowed to drop into the perforated parts pan where they are retained until
reused or discarded
Tempo Products Co. offers this brakel clutch service vacuum Model 7515 for
dry recovery of asbestos fibers The vacuum
is equipped with a stage filtration system with secondary safe protection that is said to assure maximum asbestos filter entrapment Euch unit includes complete instructions and all elements necessary for the safe collection and disposal of asbestos fibers According to the manufacturer it has been certified to comply with current regulations by un environmental laboratory
when used as instructed

Industrial vacuum cleaner bags containing asbestos dust and cloths used for wiping brake and clutch assemblies should be sealed in plastic bags and labeled with the following warning label printed in letters of sufficient size and contrast to be readily visible and legible Caution contains asbestos fibers Avoid breathing dust Breathing asbestos dust may cause as-
bestosis and cancer
All floor cleaning in areas where brakes and clutches are repaired should be done with a high efficiency industrial
vacuum cleaner

Compliance to this law will mean not only a safer shop for your employees
but it will mean a cleaner and neater
shop Also be sure your employees understand the severity of this problem so that compliance procedures become
standard operating methods in your shop
