3.0 JOB HAZARD ANALYSIS (continued) In order to control exposures at the site, work practices and the use of personal protective equipment/procedures will be required as outlined in section 5 of this plan. 3.1 Chemical Hazard Sites which have contaminated material contain a number of chemicals that may cause direct bodily injury if exposures are at levels in excess of recommended exposure limits. It is not expected that these limits will be approached or exceeded during this UST removal operation. However, there are four routes of exposure or pathways by which toxic chemicals can enter the body: skin punctures, ingestion, eye and skin absorption and inhalation. The preliminary evaluation of the property around the UST area did not reveal obvious signs of immediately dangerous to life and health conditions nor any reason to suspect that other chemicals might be present. The proper use of the personal protective equipment in conjunction with the monitoring equipment and the work procedures as described in this SSP should minimize the potential for over exposure of personnel to any of these hazardous substances. 3.1.1 Skin Puncture Skin punctures by pointed objects, such as broken glass or work- related tools, can be avoided by wearing safety boots, long - pants, a long sleeve shirt, a hard hat, gloves, and shatter resistant eye protection. 3. 1. 2 Ingestion Worker may ingest materials unintentional when they handle food, drink, smoke, bite fingernails, etc., after contact with the material and before thoroughly washing their hands. This can be avoided if worker wash their hands prior to any of these activities. 3.1.3 Eye and Skin Absorption The skin is a major protective barrier to all organs of the body. The exterior layer of the skin generally prevents foreign materials from enter the body. However, corrosive chemicals can damage the exterior layers of the skin and cause chemical burns. Some chemicals may dry the skin and cause dermatitis. Other chemical are able to penetrate the intact skin and enter the bloodstream.
