High-Rise Glass Glazing & Installation Checklist

Inspect vacuum lifter pads for cuts, tears, or debris before each lift. Replace damaged pads immediately.

Verify vacuum lifter battery is fully charged before starting work. Ensure sufficient charge for the day's planned lifts.

Confirm vacuum gauge is functioning correctly and displays adequate vacuum pressure (minimum 80% of rated capacity) before lifting.

Test audible and visual low-vacuum alarms before each use. Ensure alarms activate at the manufacturer's specified threshold.

Verify the vacuum lifter's rated capacity exceeds the weight of the glass panel being lifted, with a safety factor of at least 2:1.

Inspect all vacuum hoses and connections for leaks or damage. Replace any compromised components immediately.

Review vacuum lifter maintenance records to ensure regular inspections and servicing are up-to-date.

Verify the emergency vacuum release mechanism is functional and easily accessible in case of power failure.

Confirm all operators are trained and certified in the safe operation of the specific vacuum lifter model being used.

Assess weather conditions (wind speed, rain) and halt glazing operations if conditions exceed the vacuum lifter's or glass panel's safe operating limits.

Determine maximum allowable wind speed for glazing operations based on glass size, vacuum lifter capacity, and site-specific conditions. Use an anemometer to measure wind speed.

Monitor wind gust frequency and intensity. Suspend glazing operations if gusts exceed 75% of the maximum allowable wind speed.

Review updated weather forecasts at least every 4 hours to anticipate changes in wind conditions and adjust work plans accordingly.

Ensure glass panels are securely stored and protected from wind exposure before installation. Use appropriate bracing and tie-downs.

Identify and mitigate potential wind obstructions (e.g., adjacent buildings) that could create localized wind turbulence.

Monitor temperature extremes (high and low) that could affect vacuum lifter performance or glass panel integrity. Consult manufacturer specifications.

Suspend glazing operations during heavy rain or snow to prevent slippage and reduced visibility.

Monitor humidity levels, as high humidity can affect vacuum lifter performance. Consult manufacturer specifications.

Verify a site-specific wind action plan is in place and communicated to all personnel involved in glazing operations.

Ensure a clear emergency shutdown procedure is in place and understood by all personnel in case of sudden adverse weather conditions.

Verify perimeter guardrails are installed and properly secured on all open edges where glazing is taking place. Ensure guardrails meet OSHA height requirements (42 inches +/- 3 inches).

Inspect safety nets for proper installation, adequate overlap, and sufficient clearance below. Ensure nets are free from damage or debris.

Ensure all glaziers are wearing properly fitted personal fall arrest systems (PFAS) with appropriate anchorage points. Inspect harnesses and lanyards for damage.

Verify anchorage points for PFAS are certified to withstand a minimum of 5,000 pounds per employee attached or designed by a qualified person.

Establish controlled access zones (CAZ) where guardrails or safety nets are not feasible. Clearly mark CAZ boundaries with warning lines or control lines.

Ensure warning lines are erected at least 6 feet from the edge of the roof or working surface. Verify lines are flagged every 6 feet.

Are 3.5-inch toe boards installed on all open sides to prevent tools and materials from falling (where applicable)?

Provide edge protection (e.g., edge protectors, gloves) to prevent cuts and lacerations when handling glass panels.

Establish and enforce a strict drop zone management plan to prevent tools and materials from falling to lower levels.

Maintain good housekeeping practices to prevent slips, trips, and falls. Keep walkways clear of debris and obstructions.

Verify all personnel are wearing ANSI-approved hard hats in good condition.

Ensure all personnel are wearing ANSI Z87.1-approved safety glasses with side shields.

Confirm glaziers are wearing cut-resistant gloves when handling glass panels.

Ensure all personnel are wearing high-visibility clothing (Class 2 or 3) that meets ANSI 107 standards.

Verify all personnel are wearing steel-toed boots that meet ASTM F2413 standards.

Inspect fall protection harnesses for proper fit, damage, and wear. Ensure D-rings are in good condition.

Ensure personnel are wearing appropriate clothing for the weather conditions (e.g., rain gear, thermal layers).

Encourage the use of sunscreen and hats to protect against sun exposure.

Assess the need for respiratory protection based on site-specific conditions (e.g., dust, fumes). Provide appropriate respirators if required.

Verify that PPE is properly maintained, cleaned, and stored when not in use.
