Respirators Material Safety Data Sheets

Inhalation of certain fine dusts may constitute a health hazard. For example, exposure to silica, asbestos, and beryllium oxide dusts over a period of time results in the potential risk of lung disease. OSHA regulations specify the allowable levels of exposure to ingestible and respirable materials. Material Safety Data Sheets, OSHA form 20, available from manufacturers, provide information about hazards, precautions, and storage pertinent to specific refractory products. 

It is the responsibility of the operator to read and understand relevant health and safety information (e.g., material safety data sheets) before sampling. The operator must wear appropriate protective clothing for the materials to be sampled the operator should be protected from the material and the material should be protected from the operator. If specific safety precautions and equipment (e.g., respirator) are required, then the operator must be properly trained in the use of the specified equipment and procedures. 

Inhalation toxicology studies with fihrils made from p-aramid have been documented. Responses were detected, but the interpretation of these studies were regarded as controversial. There is some evidence for the biodegradabihty of p-aramid respirable-sized fiber-shaped particulates, which concept was supported in subsequent studies. Actually, material safety data sheets report the possibihty of lung injury, if fiber dust is inhaled for a prolonged time. On the other hand, aramids are not considered to be dangerous by skin contact or by ingestion. 

Proper ventilation will aid in reducing vapor concentrations of solvent to acceptable exposure limits. In areas of higher vapor concentrations workers should be trained and equipped with appropriate respirators as per the recommendations of the solvent manufacturer. Proper safe handling procedures will be outlined in the Material Safety Data Sheet (MSDS). 

When engineering controls cannot completely eliminate the risk of exposme to solvents, affected employees will need to wear PPE. Chemical splash goggles, face shields, gloves, coveralls, aprons, shoe covers, and respirators are all examples of protective equipment. Refer to the product s material safety data sheet for PPE recommendations.
