Notes

Systems to Control

Pre-contact:
Engineering Control:
Elimination/Minimization
Enclosure of the Hazard

Administrative Control
Exposure time limitations, safe work practices, signs and signage, training and education

ladders - short duration

Information
Training
Instruct
Supervision

Point of contact:
PPE
last line of defense but least effective

CONSTRUCTION SITE PREMISES
General Provisions
- protect every workingman
- conserve valueable manpower resources and prevention of loss of life

ACCIDENT PREVENTION
- real factor in the economic success of any construction job
- methods of prevention
- ample evidence
- profitable
- lower cost and greater efficiency

GENERAL CONSTRUCTION SITE REQUIREMENTS
- accident prevention is a legal requirement
- complete understanding between the owner and the contractor
- practical experience in running construction jobs
- accident prevention as part of advance planning
- protection of workers and the public

CONSTRUCTION HAZARDS
- open excavation
- falling objects
- welding operations
- dust dirt
- temporary wirings
- temporary overhead electrical lines

CONSTRUCTION SITE REQUIREMENT
- have fire, emergency or danger sign and safety instructions of standard colors and sizes visible at all times
- SAFETY SIGNAGE
-WORKERS WELFARE FACILITIES
- source of drinking water
- sanitary and washing facilities
- living accommodation
- separate sanitary sites

- CONSTRUCTION SITE HOUSEKEEPING
- a palce for everything and everything in it's place
- it is everybody's business to observe the workplace
- it is important because it lessens accidents and injuries
- 5S is a very practical, simple

What are sins of DISORDER
1. cluttered and poorly arranged areas
2. untidy piling of materials
3. piled-on material damaging other material
4. items no longer needed
5. blocked aisle ways
6. material stuffed in corners and out-of-the-way places
7. materials gathering rust and dirt from disuse
8. excessive quantities of items
9. overcrowded bins and containers
10. overflow storage areas and shelves
11. broken containers and damaged materials

5S
- safety
-quality improvement
- efficiency
- productivity improvement
- workers feel good in their second home
- easy knowledge of process abnormalities
- work improvement
- company image - cleanliness/orderliness/beautification

- ELECTRICAL SAFETY
What is electricity?
- a versatile form of energy

Dangers from electricity
- shock
- burn
- fire

Electrical Hazard
- an electrical source of danger
- a potential risk for an electrical accident

What are the types of electrical hazard?
There are two types:
physical hazard: is a problem in which the equipment or area surrounding it poses a threat due to physical condition
behavioral hazard: is when a person, by the way they act or behave

Physical Hazards:
- wet floors
- bare or frayed wires
- overloaded circuits
- an electrical cord under a rug or trap
- energized equipment with exposed circuit

Behavioral
- indifference
- lack of knowledge
- working while stressed
- taking shortcuts or risk

Resistance of Materials
Most metals - 0 to 50 ohms
human body - 100 ohms
human body (damp) - 400 - 600 ohms
