E N D
Operational Hazards The overall objective for this module is that the participants will recognize general safety hazards and safe work practices related to fixed facility work
Overview • Common safety hazards • Safe work practices • Preventing and treating heat and cold stress • Proper lifting and handling • Confined space procedures
Expectations • Define a general safety hazard • Identify general methods to prevent accidents • Recognize general safety-hazard categories and related precautions • Identify symptoms and prevention measures for heat stress and cold stress
Expectations • Recognize biological hazards • Recognize ergonomic hazards • Identify general precautions for confined space work • Identify potential fire hazards and fire prevention strategies
Operational Hazard • Anything on or around a work site which may compromise worker safety or health if appropriate control measures are not implemented
Prevention of Accidents • Aware of changing conditions • Take initiative to correct potential safety hazards • Understand the task • Watch for weather conditions, wind direction and unusual odors
Ten Common Causes of Accidents • Poor instructions • Poor planning • Improper design • Improper equipment provided or used • Failure to follow instructions
Ten Common Causes of Accidents • Neglect or improper use of equipment • Faulty equipment • Untrained personnel • Uncooperative personnel • Uncontrollable or unexpected outside agents (e.g., weather or sudden illness)

Lifting Safely Back injuries are the Nation’s #1 Workplace Safety Problem
Lifting Safely • Preparing to Lift • Clear obstacles away • Heft to check weight • Performing the Lift • Square with object • Balance • Squat, bend knees, grip object, tighten abdomen USE YOUR LEGS
Safe Lifting Tips • Don’t life objects over your head • Don’t twist • Pace yourself • Don’t reach over an obstacle • Follow your workplace safety guidelines
Common Site Hazards • Heat stress • Cold stress • Biological hazards • Confined spaces
Heat Stress • Occurswithin 15 minutes • Factors to consider: • Poses serious health threats • Environmental conditions (including air temperature and humidity) • Clothing • Workload • Individual worker characteristics
Forms of Heat Stress • Heat Syncope • Heat Cramps • Heat Exhaustion • Heat Stroke • Heat Rash • Transient Heat Fatigue
Heat Syncope • Fainting • Frequently occurs when a worker is not acclimated to hot environments
Heat Cramps • Caused by excessive loss of salt during sweating • Symptoms • Muscle spasms in the extremities, abdomen, or back
Heat Cramps • Treatment • Massaging the cramped muscles • Replenishing the victim’s water and electrolytes
Heat Exhaustion • Victim suffers from a severe lack of fluids and salts • Symptoms • Pale or flushed skin • Moist skin • Headache • Fatigue • Nausea • Normal or slightly elevated temperature • Profuse sweating
Heat Exhaustion • Treatment • Victim must rest in a cool place • Drink water
Heat Stroke • Most severe form of heat stress • Caused by a failure of the body’s temperature regulation mechanism
Heat Stroke • Symptoms • Absence or reduction of sweating • Elevated body temperature • Skin is red, hot, and dry • Dizziness • Nausea, • Confusion • Treatment • Medical attention as soon as possible
Heat Rash • Prickly heat and transpires in a hot, humid environment where sweat is unable to evaporate • Prevention • Worker must periodically rest in a cool place • Skin must be bathed regularly and kept as dry as possible
Transient Heat Fatigue • Causes temporary discomfort accompanied by mental and/or psychological strain, which affects task performance, coordination, and alertness • Treatment • Lessened by gradual adjustment to heat conditions
Prevention of Heat Stress • Maintain adequate water intake • Take breaks in a cool place • Learn the signs and symptoms of heat stress and respond at the earliest point of detection • Schedule heavy work or work in PPE for cool times of the day • Move work location to shade or cooler area
Prevention of Heat Stress • Have workers drink 16 ounces of water before beginning work • Urge workers to drink a cup or two of water every 15 to 20 minutes • Weigh workers before and after work to determine if fluid replacement is adequate
Cold Stress • Superficial Frostbite • Deep Frostbite • Hypothermia
Superficial Frostbite • Characterized by the freezing of only the outer skin layer • Treatment • Protect the exposed area by placing uncovered fingers under opposite armpits or placing bare frostbitten feet under clothes or against the skin of a companion until pain returns
Superficial Frostbite • NOTE: DO NOT’S • Warm frostbitten parts by massaging • Expose to an open fire • Soak in cold water • Rub with snow
Deep Frostbite • Characterized by the freezing of tissue beneath the outer skin layer • Treatment • Protect frozen parts from further cold exposure • Keep victim warm while being transported to a hospital • NOTE: Protect frozen parts from additional injury Do not attempt to thaw them in the field
Hypothermia • Characterized by subnormal body temperatures • Treatment • Keep victim warm • Give warm beverages or soup • NOTE: Alcohol consumption increases risk • NOTE: Death can occur
Prevention of Cold Stress • Wear proper clothing • Maintain a proper diet • Use shelter • Monitor worker’s conditions
Biological Hazards • Ticks • Bees and Wasps • Spiders and Scorpions • Snakes • Rabid Animals
Ergonomic Hazards • Study of how a human physically and mentally interacts with the workplace • Notify manager or supervisor of hazards
Material Handling • Use mechanical devices • Drum dollies • Pallet dollies • Push carts and dollies so you can see ahead and around the load
Material Handling • Do it the easy way • Push rather than pull • Bend your knees, not your back • Step with legs, don’t rotate • Use ladders for high loads • Wear steel-toed boots • Pick up stacks in two steps • Don’t block your visibility
Container Handling • Hazard Recognition • Detonation, fire and explosion • Vapor generation • Physical injury caused by lifting improperly or moving containers
Container Handling • Drum Handling Safety • Use forklifts, dollies and pallet jacks • Wear protective PPE • Check drum for sharp edges or rust • Plan the move and clear obstructions • Manually lift with good technique • Do not handle or move if safety is questioned
Confined Space • Adequate size and configuration for employee entry • Limited means for entry and exit, one and/or small openings • Is not designed for continuous employee occupancy, such as small utility spaces
Confined Space Permits • Contains or has the potential for containing a hazardous atmosphere • Contains a material that has a potential for engulfing an entrant • Has an internal configuration such that an entrant could be trapped • Contains any other recognized serious safety hazard
Atmospheric Hazards • Flammable gas in excess of 10% LEL • Airborne combustible dust which meets LEL • Oxygen concentration below 19.5% or in excess of 23.5% • An atmosphere which could result in employee exposure in excess of PEL
Other Potential Hazards • Mechanical Hazards • Slips, Trips and Falls • ART - There is an “art” to preventing slips, trips and falls • Awareness • Responsibility • Traction
Slips, Trips and Falls • Awareness • Be alert throughout the workday • Look ahead from the knee level • Know where there are existing step hazards • Look for wet areas • Look for obstructions and electrical cords
Slips, Trips and Falls • Responsibility • Everyone in the workplace must assume responsibility for keeping a safe work area • One is more likely to be injured from a slip, trip, or fall than from hazardous chemicals • Take the time to remove the hazard or notify those who are able to do so
Slips, Trips and Falls • Traction • Be aware of changing conditions • Maintain good footwear with traction • Enhance traction by using rough surfacing, lowering slopes of ramps and replacing low-traction surfaces
Fire Safety (Uniform Fire Code) • Check with your local fire officials • Flammables and combustibles may be a large proportion of waste accepted • Multiple hazards PROPER STORAGE IS A MUST !
