Waste Storage • Waste oil, transmission fluid, power steering fluid, and brake fluid goes in the waste oil drum- it is clearly marked. • Waste anti-freeze and water goes in the waste anti-freeze drum-clearly marked. • Waste chemicals must be stored in their original container and disposed of professionally.
Battery Safety • Car batteries contain Electrolyte • Sulfuric Acid-Caustic (will burn your skin on contact) • Distilled Water-(No minerals or foreign particles) • The process of charging and discharging in a battery causes the electrolyte to create Hydrogen gas. • Highly flammable and explosive if in concentrations. • No spark, open flames, or heat sources around batteries.
Safe Battery Service • When removing or reinstalling a battery • To prevent sparks which could ignite the hydrogen around the battery • Disconnect the negative FIRST • Reconnect the negative LAST
Jump Starting a car • Pull the cars together • Stretch out your cables so the ends do NOT touch • Connect positive cable (red) to the live car’s positive post on the battery (+) • Connect the other end of the positive cable to the dead car’s positive post on the battery (+) • Connect the negative cable (black) to the live car’s negative post on the battery (-) • Make the last negative connection (black) (-) on the dead car’s ground (clean, unpainted, non-moving, metal part as far away from the battery as possible.
