Study Notes

OSHA Mission

Mission: Ensure every worker returns home whole and healthy daily.

Electricity and Electric Shock

Electricity flows in closed circuits; shock occurs when the body becomes part of the circuit.

Fall Protection Measures

Do not sit, lean, or step on skylight lenses or covers over holes.
Securely cover all holes before leaving work areas.
Utilize Personal Fall Arrest Systems (PFAS) for heights over six feet.

Hazard Avoidance Steps

Implement workplace and engineering controls prior to considering Personal Protective Equipment (PPE).

Scaffolding Types

Main types of scaffolds: aerial lifts, supported scaffolds, and suspended scaffolds.

Crane and Derrick Safety for Personnel

Cranes must have a firm foundation, be level within 1% of grade.
Movement of personnel platforms must be slow and cautious; use rotation-resistant ropes.
All brakes and locks on cranes must be engaged when stationary.

Protection from Power Tool Hazards

Use appropriate PPE when operating power tools that produce flying debris or sparks.

Definition of Excavation

Excavation is any man-made cavity, depression, trench, or earth cut formed by earth removal.

Proper Lifting Techniques Training

Training must include the spine, muscles, and joints anatomy.
Emphasize safe lifting postures and timing.

Mechanical Demolition Equipment

Involves tools like wrecking balls and jackhammers.

OSHA Electrical Standards

Based on the National Electrical Code (NEC).

Types of Electrical Injuries

Main types include: electrocution, electric shock, burns, and indirect injuries (e.g., falls).

Severity of Electric Shock

Severity factors: length of exposure, amount and frequency of current, and current path.

Electrical Burns

Most severe burns typically occur on hands due to direct current contact.

Identification of Hot Wires

Hot wires are usually black or red and ungrounded, posing shock hazards.

Causes of Electrocutions

Over 50% of electrocutions result from contact with energized power lines.

Flexible Cord Requirements

Flexible cords must be rated for hard or extra hard usage.

Common OSHA Violations

Most frequent violation: improper grounding of circuitry and equipment.

Electrical Safety Program Elements

Essential elements include: recognize hazards, evaluate risks, and control dangers.

Handling Damaged Portable Electric Tools

Damaged tools must be removed from service and tagged "Do Not Use."

Adapter Use for Electrical Connections

Acceptable to use an adapter with a three-prong plug when connected to a known ground.

Power Tool Safety Rules

Five rules include: maintain tools, inspect before use, follow manufacturer instructions, use proper PPE, and select the right tool for the job.

Guarding Live Parts

Live electric equipment operating at 50 volts or more must be protected from contact.

Lockout/Tagout Procedures

Circuits must be locked or tagged when personnel are exposed to de-energized equipment or circuits.

Low Voltage Hazards

Low voltage does not imply low hazard; risks still exist.
