Study Notes
Safety Culture and Employee Turnover
- Companies with robust safety cultures experience reduced employee turnover.
Unsafe Working Conditions
- Examples of unsafe conditions include poor lighting, excessive noise, and inadequate guards for moving machinery.
Job Hazard Analysis
- Job safety analysis involves breaking down a job into tasks and examining each for potential hazards.
Understanding Risk
- Risk is defined as the measure of an event's probability, consequences, and exposure.
Fall Protection Measures
- To protect against falls from floor openings, the standard method is to cover the hole and clearly label the cover.
Safety Harness Guidelines
- The D-ring on a safety harness should be positioned between the shoulder blades for optimal use.
Personal Fall Arrest System Inspection
- A personal fall arrest system must undergo monthly inspections conducted by a competent person.
Lanyard Use
- Non-shock-absorbing lanyards are utilized for positioning rather than fall protection.
Ladder Safety Practices
- When setting up a ladder, it should extend at least 3 feet above the platform or roof it rests against.
Overhead Work Safety
- Protective measures such as toeboards, debris nets, or canopies are necessary to prevent falling objects from striking individuals below during overhead work.
Material Stacking Guidelines
- Stacking materials like bricks should adhere to a maximum height-to-base ratio of 4:1.
Soil Safety Regulations
- Benching systems are not permitted in Type C soils, which are known to be more unstable.
Excavation Soil Classification
- All soil in an excavation should be classified as Type C soils unless specific information indicates otherwise.
Excavation Inspection Requirements
- A competent person must conduct daily inspections of excavations to ensure safety.
Electrical Grounding Systems
- The three-wire system is commonly employed for grounding and protecting against electrical shock.
Lockout/Tagout Procedures
- Lockout/tagout procedures are used to protect workers from hazardous energy during interaction with machines.
Use of Polarized Receptacles
- Polarized electrical receptacles are designed for use with double-insulated tools.
Lock Removal Protocol
- In lockout/tagout situations, only the individual who applied the lock and tag is authorized to remove them.
Hard Hat Materials
- Hard hats are typically constructed from fiberglass or reinforced plastic for adequate protection.
Hearing Protection Guidelines
- Hearing protection is recommended if a worker must raise their voice to be heard from a distance of 2 feet (61 cm).
Asbestos Exposure Protocol
- Workers must report asbestos exposure to a supervisor and avoid disturbing the material.
Respiratory Protection
- A half mask or mouthpiece equipped with a mechanical filter is recommended for environments with dust or solid particle hazards.
Lead Exposure Sources
- Lead may be present on job sites, particularly from sources like paint.
Pathogen Exposure Risks
- Hepatitis can be transmitted through contact with infected blood.
Heat Stroke Symptoms
- Symptoms of heat stroke include an extremely high body temperature, indicating a life-threatening condition.
Welding Safety Practices
- During welding operations, it is crucial to ensure ample fire extinguishers are readily accessible.
Fire Extinguisher Classifications
- For electric motor fires, a Class D fire extinguisher is appropriate.
Confined Space Entry Regulations
- An entry permit is necessary before accessing any permit-required confined space.
