Asbestos NESHAP Inspection and Safety Procedures Course Chapter 9 Other Safety Considerations 2014
Topics • Miscellaneous Hazards, cont. • Chemical • Biological • Confined Spaces • Claustrophobia • Noise • Machinery • Thermal • Fire • Drowning • Heat Stress • Climbing/Fall Hazards • Ladders/Scaffolds • Roofs • Fall Protection • Working Surfaces • Illumination • Electrical Hazards • Miscellaneous Hazards • Falling Objects • Structurally Un-sound Buildings
Medical Service and First Aid In absence of infirmary, clinic, hospital, or physician, that is reasonably accessible, a person onsite must be certified in first aid.
Telephone numbers of emergency services posted Eye washes placed where necessary Medical Service and First Aid
HEAT STRESS • Dehydration • Cramps • Heat Exhaustion • Heat Stroke
Dehydration - Cramps • Body loses water • Can not cool fast enough • Feel weak and thirsty • Painful muscle cramping • Fatigue • Replenish fluids
Heat Exhaustion • Feel tired and dizzy • Feel nauseous and faint • Skin may be damp, cool, clammy, flushed. • Replenish fluids if able to drink without choking. NOT ice water!
Heat Stroke • May be confused, convulsing, unconscious • Hot dry skin • Elevated body temperature • TRUE EMERGENCY GET HELP • Cool victim ASAP… shade, water, ice. • Nothing by mouth
Prevention • ENGINEERING CONTROLS • Ventilation • Spot cooling • Shielding • Personal cooling devices • OTHERS • Increasing fluid intake • Using PAPR • Gradual Acclimatization
Climbing Hazards • Examine before use • Possible pre-demo cutting of internal supports
Capacity • Support own weight and 4X the maximum intended load. • Suspension rope & hardware, 6X the maximum intended load. • Stall load of scaffold hoist not to exceed 3X its rated load. • Designed by a qualified person and built and loaded to design.
Safe Scaffolding Tips • Don’t overload your scaffold. • Don’t ride on moving scaffold. • Use adequate guardrails. • Inspect scaffold frequently.
Step Ladders • Type I - Industrial (3-20’) - utilities, contractors, etc. • Type II - Commercial (3-12’) - painters, offices, etc. • Type III - Household (3-6’) Stepladders > 20’ are not allowed
Extension Ladders • Length cannot exceed 60’ • Tied off and extend at least 3’ above working surface • Safe angle (4V:1H) • Must overlap at least 3’ in middle
Ladder Safety • Never use two step ladders as support for scaffold boards • Only one employee at a time is permitted to work on a ladder • Inspect periodically • Slip resistant base
Ladder Safety • Locked into position? • Electrical source nearby? • Proper lean ratio with extension ladders?
Roofs • Roofs can present multiple fall hazards • Stepping off edge • Falling through (skylights) • Slipping on sloped roofs
