Personal Protective Equipment • PPE provides an effective means for protecting technicians from hazardous situations • Engineering and environmental controls provide another layer of protection. • The primary purpose of PPE is to prevent exposure to hazards when engineering or environmental controls cannot. © 2012 Delmar, Cengage Learning

Outerwear • • • Safety hats Safety glasses Fire-retardant clothing Safety shoes Hearing protection Gloves Face shield Chemical monogoggles Slicker suit Total encapsulating chemical protective suit © 2012 Delmar, Cengage Learning

Hand Protection • Many of the gloves used by chemical technicians have a wide variety of operational limitations; one type of glove cannot be used for every job. • Glove charts will provide all the information you need to select the right glove. © 2012 Delmar, Cengage Learning

Eye Protection • Wear approved eye protection where minimum eye protection is insufficient. • Wear approved face protection where face and eye injury is a concern. © 2012 Delmar, Cengage Learning

Foot Protection • The design composite of the soles must be chemical resistant, puncture proof, slip resistant, abrasion resistant, and provide cushioning support. • Footwear must pass performance tests for impact and compression according to ANSI Z 41. 1 -1967 and meet class 75 requirements for men’s and women’s shoes. © 2012 Delmar, Cengage Learning

Ear Protection • The CPI regulates noise levels over an eight-hour, time weighted average (TWA) work shift to be around 85 d. BA. • Exposure should never exceed 115 d. BA. © 2012 Delmar, Cengage Learning

Hazards in the Workplace • • • Burning Exploding Cutting Electrocution Impaling Tripping Toxic chemicals Chemical burns Asphyxiants © 2012 Delmar, Cengage Learning

Emergency Response • Four levels of PPE, Level A is the highest requiring TECP, Level B deals with chemical exposures that are not considered extremely toxic unless absorbed through the skin, Level C is used when the hazard is determined to not adversely affect human skin, Level D is the minimal amount of protection. © 2012 Delmar, Cengage Learning

Written Respiratory Protection Programs • Fit testing is a procedure that ensures the respirator forms a good seal on the technician’s face. During fit test training the technician learns the following: • • • Which respirator will be used in their area Which respirator fits their face How to properly don a respirator How to select a respirator Specific hazards in their assigned units © 2012 Delmar, Cengage Learning

Air-Purifying Respirator • Designed to remove specific contaminants or organic vapors from the air. • Half-face covers the mouth and nose. • Full-face covers the eyes, mouth, and noise. © 2012 Delmar, Cengage Learning

Air-Supplying Respirators • Designed to be used in oxygen-deficient atmospheres and to provide protection. • Comes in two designs: self-contained breathing apparatus and hose line respirators. © 2012 Delmar, Cengage Learning

Selecting a Respirator • Will the respirator I choose protect me from the environment I will be working in? • The process technician is required to reference the MSDS. © 2012 Delmar, Cengage Learning

Caring for and Using Respirators • OSHA inspectors will cite the company for improper storage of a respirator. • SCBA users typically train monthly on donning and using the air-supplying respirator. • When a respirator is used the technician should perform a positive or negative fit test. © 2012 Delmar, Cengage Learning

• Air-purifying respirators remove contaminants from the atmosphere by putting a filter between the contaminant and the respiratory tract of a technician. • Air is purified through mechanical filtration or chemical absorption. • Air-purifying respirators do not provide oxygen, so the atmosphere’s oxygen content must not be below 19. 5%. © 2012 Delmar, Cengage Learning

Self-Contained Breathing Apparatus • Most SCBA have full-face pieces and weigh between 35 and 45 lbs. • SCBAs provide a self-contained air supply that will last 30 to 60 minutes. © 2012 Delmar, Cengage Learning
