OSHA's Mission

the mission of OSHA is to assure safe and healthful working conditions for working men and women by setting and enforcing standards and by providing training, outreach, education, and assistance.

What are GFCI's (ground fault circuit interrupters) designed to do?

they are designed to sense an imbalance in current flow over the normal path -they have a special sensor that monitors the strength of the magnetic field around each wire in the circuit when the current is flowing -the field is proportional to the amount of current flow

the basics of scaffold safety

-every supported scaffold and its components must support, without failure, its own weight and at least four times the intended load (where intended load= sum of the weights of all personnel, tools and materials that will be placed on the scaffold) -each rope on a suspended scaffold must support the scaffold's weight and at least 6 times the intended load -scaffold platforms must be at least 18 inches wide and guardrails must be used if working 10 ft or mor above ground level. guardrails must be between 39 and 45 inches high and midrails must be installed halfway between the top rail and the platform surface.

Types of OSHA Inspections

what is an extension ladder

"portable ladders" usually have two sections that operate in brackets or guides allowing for adjustable lengths -because extension ladders are not self-supporting, they require a stable structure that can withstand the intended load

some of the things OSHA does to carry out its mission

- developing job safety and health standards and enforcing them through work-site inspections -providing training programs to increase knowledge about occupational safety and health

effects of electric current on the human body

-1 milliamp: faint tingle -5 mA: slight shock felt, not painful but disturbing -6-25mA: painful shock, loss of muscular control -9-30mA: the freezing current or the "let-go" range. individual cannot let go, but can be thrown away from the circuit if extensor muscles are simulated -50-150mA: extreme pain, respiratory arrest, severe muscular contractions. death is possible -10,000 mA: cardiac arrest, severe burns, death is probable

How GFCI's work:

-if the current flowing in the black (ungrounded) wire is within 5 mA of the current flowing in the white (grounded) all the current will flow in the normal path -if the current differs by more than 5mA, the GFCI will quickly open the circuit (if the equipment grounding conductor is properly installed and maintained, this will happen as soon as the faulty tool is plugged in

GFCI: Circuit Breaker type

-includes the functions of a standard circuit breaker with the additional function of a GFCI -installed in a panelboard and can protect an entire branch circuit with multiple outlets -a direct replacement for a standard circuit breaker of the same rating

GFCI: Receptacle type

-incorporates within one device one or more receptacle outlets, protected by the GFCI -popular and inexpensive -most are of duplex type -can protect additional non-GFCI type receptacles connected "downstream"
