Chemical Exposure
How can you avoid exposure?
How can you avoid exposure? • • Hands? Eyes? Clothes? Face?
How can you avoid exposure? • Procedurally – Use small amounts of chemicals – Follow directions exactly – Make sure equipment is not broken – Be aware of NFPA diamond information – Look up information on MSDS

Prevention is better than cure • OSHA – Occupational Safety and Health Administration • NFPA diamond • MSDS – Material Safety Data Sheets
Reading a NFPA diamond • Blue is for level of Health Hazard • Red is for level of Flammability • Yellow is for level of Chemical Reactivity • White is for special codes for unique hazards
Reading a NFPA diamond • The blue, red and yellow portions will rate he hazard from 0 to 4 with 4 being the most dangerous. • The white “special notification” symbols include OX for oxidizer, W to symbolize an unusual or dangerous reaction with water or SA to signify Simple Asphyxiant gas
