OSHA 10 Module 2 Questions And Answers

OSHA 10 Module 2 Answers Most OSHA electrical safety guidelines and regulations for construction are contained in Subpart K, CFR 1926, Which is based on: The National Electrical code How easy or difficult it is for electricity to flow through a material measured in ohms Volts electrical pressure( measured of electrical force) Amps The volume or intensity of the electrical flow Current Electrical movement ( measured in amps) Circuit The complete path of the current; includes the electricity source, the conductor, and the output device ( such as tool, light etc.) Resistance Meaured in Ohms; the resistance of a material to the flow of electricity. Conductors Material with lit tle resistance Gorund A conducting connection, whether intentional or accidental, between an electrical circuit or equipment and the earth, or to some conducting body that serves in place of the earth. Insulators Material with high resistance to electricity; often used to prevent electricity from getting to unwanted places. What Causes a shock A shock ocurs when your body becomes part of or completes a circuit Shocks can occur when your body completes the path with: 1. Both wires of an electric circuit 2. One wire of an energized circuit and the ground 3. A metal part that accidentally becomes energized 4. Another conductor that is carrying a current How does electricity Travel Electriicty travels in a closed circuit What are four of the most common types of Electrical injuries Four of the most common types of electrical injuries are. 1. burns 2. Electrical shock 3. Falls 4. Electrocution Electrical accidents are usually caused by a combination of three fac tors: 1. Unsafe equipment and/ or installation 2. Workplace made unsafe by the environment( think electrical equipment in a rain storm) 3. Unsafe work practicess Electrical Burn occurs When heat is generated by the flow of electrical current through the body, thus causing tissue damage. Arc or Flash burns occurs when electrical arc or explosion occurs with enough intensity to burn someone nearby thermal contact burns are caused By skin coming in contact with overheated electrical equipment, or when clothing ignites from a spark or other electrical incident.
