Fall Protection
for HVAC Technicians

Falls - The #1 Construction Killer

Falls account for approximately one-third of all construction fatalities each year. HVAC technicians routinely work at elevation: rooftop equipment, elevated mechanical rooms, ladders, scaffolding, and catwalks. Fall protection is a life-safety requirement, not a formality.

OSHA Fall Protection Trigger Heights

Three Methods of Fall Protection

OSHA requires employers to use one of three acceptable fall protection systems:

1. Guardrail systems - Physical barriers (top rail at 42�3 inches, mid-rail, toeboard) around elevated work areas. Preferred method when feasible.
2. Safety net systems - Nets installed below work areas to catch falling workers
3. Personal fall arrest systems (PFAS) - Full-body harness, connecting lanyard/SRL, and anchor point

Ladder Safety - OSHA 29 CFR 1926.1053

Ladder accidents cause thousands of injuries and hundreds of deaths each year. Follow these requirements every time:

Portable Straight/Extension Ladders

• 4:1 angle rule - Set ladder at 75.5? from horizontal: for every 4 feet of working height, the base should be 1 foot away from the wall
• 3-foot extension - Ladder must extend at least 3 feet above the landing when accessing an upper level (like a roof)
• Secure the ladder - Tie off top and bottom, or have a second person hold the base
• Three points of contact - Two hands and one foot, or two feet and one hand, at all times while climbing
• Face the ladder - Always face toward the ladder when ascending and descending
• No overloading - Never exceed the duty rating (Type III=200 lbs, Type II=225 lbs, Type I=250 lbs, Type IA=300 lbs, Type IAA=375 lbs) including your body weight, tools, and materials
• No top 3 rungs - Never stand on the top three rungs of a straight ladder

Stepladders

• Never stand on the top cap or top two steps
• Fully open the ladder and lock the spreader arms before use
• Do not lean a closed stepladder against a wall and climb it
• Face the ladder when working; do not overreach to the side

Rooftop HVAC Work

Commercial rooftop HVAC service is one of the highest-risk activities for fall injuries:

• If the roof edge is within 6 feet of the work area: full fall protection required (guardrails, PFAS, or safety net)
• If greater than 6 feet from the edge: a designated safety monitor may be used (must be trained and dedicated to watching workers)
• Skylights are a leading cause of rooftop fall deaths - they look solid but many cannot support a person's weight. Guard or cover all skylights in your work area.
• Leading edges - Edges created during construction are among the most dangerous fall hazards

Personal Fall Arrest System (PFAS) Requirements

• Anchor point - Must support at least 5,000 lbs per worker, or be designed by a qualified person with 2:1 safety factor
• Full-body harness - Body belts are no longer permitted for fall arrest (they cause internal injuries); full harness required
• Self-retracting lifeline (SRL) or shock-absorbing lanyard - Must limit free fall to 6 feet and arrest force to 1,800 lbs
• Inspect before each use - Check for cuts, fraying, burns, corrosion, broken buckles
• Remove from service after a fall - Any harness or lanyard that has arrested a fall must be removed from service immediately - it may appear undamaged but internal components may have failed
