An Insulation Contractor Safety Manual provides the written safety programs, policies, procedures, and employee responsibilities needed for contractors that install, remove, repair, replace, and maintain building, mechanical, industrial, and specialty insulation systems.
Insulation contractors may work with fiberglass, mineral wool, cellulose, rigid foam, spray polyurethane foam, pipe insulation, duct insulation, equipment insulation, removable insulation, vapor barriers, mastics, adhesives, sealants, jackets, and other materials. Employees may perform work from ladders, scaffolds, aerial lifts, roofs, attics, crawlspaces, mechanical rooms, industrial facilities, and other locations with significant workplace hazards.
A properly developed Insulation Contractor Safety Manual should reflect the company’s actual insulation materials, installation methods, employees, equipment, customer facilities, construction activities, and work environments.
The safety programs needed by an insulation contractor depend on the work performed. A comprehensive manual may include programs covering:
Additional programs should be included when industrial processes, hazardous chemicals, specialized insulation materials, or customer locations create additional hazards.
Insulation work can expose employees to both physical and health hazards.
Potential hazards include:

Employees should stop work when they encounter suspect materials that have not been appropriately evaluated.
Insulation contractors may encounter asbestos-containing or presumed asbestos-containing materials while working in older buildings and industrial facilities.
Potential locations include:
Employees who may encounter these materials should receive appropriate asbestos hazard information and training.
Certain installed thermal-system insulation and surfacing materials in older buildings may be considered presumed asbestos-containing material under applicable OSHA requirements unless the presumption has been properly rebutted.
Employees should not disturb suspect insulation merely because its composition is unknown.
Work should be stopped and the material evaluated according to established procedures.
Removal of asbestos-containing thermal-system insulation is regulated asbestos work and should not be treated as ordinary insulation removal.
Companies performing asbestos work must comply with the requirements applicable to the class and type of asbestos work being performed.
Employees who are not appropriately trained, equipped, and assigned to asbestos work should not disturb known or presumed asbestos-containing insulation.
When employees encounter material suspected of containing asbestos, they should:

Employees should receive training appropriate to their work and exposures.
Training may include:
Training should be documented as applicable and updated when materials, equipment, work methods, assignments, or hazards change.
An Insulation Contractor Safety Manual should be customized to the company’s actual work rather than relying solely on a generic Construction Safety Manual.
A commercial insulation contractor installing fiberglass, mineral wool, rigid foam, and building insulation may require extensive programs for respiratory protection, PPE, ladders, scaffolds, aerial lifts, material handling, cutting tools, silica, and fall protection.
A spray-foam insulation contractor may require additional procedures for isocyanates, chemical handling, ventilation, restricted work areas, respiratory protection, protective clothing, spray equipment, spills, and occupant protection.
A mechanical or industrial insulation contractor may need additional procedures for pipe and equipment insulation, hot surfaces, process systems, asbestos awareness, scaffolding, aerial lifts, confined spaces, hazardous energy, industrial facilities, shutdowns, and contractor coordination.
Companies performing insulation removal or retrofit work should also address the possibility of asbestos-containing materials, contaminated insulation, unknown building materials, dust, mold, and other hazards encountered in existing facilities.
The manual should reflect the company’s insulation products, installation and removal methods, employees, tools, lifts, scaffolds, respiratory hazards, chemicals, industrial work, customer facilities, and other site-specific hazards.
The completed manual should provide practical procedures employees and supervisors can use while supporting OSHA compliance, employee training, JSAs, PPE selection, respiratory protection, equipment inspections, incident investigations, contractor coordination, and the company’s overall safety-management system.
