OSHA.gov stands for the Occupational Safety and Health Administration.
HERE is what you need to know for the exam:
- protection system is needed if fall will be above 6 feet.
- spotter, net, or lanyards to ensure personnel will not fall
- On sloped roofs you need to use harnesses and safety rope. Use non-slip shoes and gloves on metal roofs.
- Safe design–follow National Electric Code (NEC), IEEE, ANSI, Local codes.
- It is typical for PV systems to operate at high voltages–beware of shock hazard.
- Install wire in conduit if exposed to people or weather.
- When working with batteries use eye protection above all else; gloves that cover forearms, and always make sure it is in a well ventilated area.
- Never short the + and – terminals together on a battery. Arcing will occur.
- Attics of homes can be hot, be careful when entering attics for an extended time period.
PART 1926 Subpart E in the OSHA (General Construction)
All individuals working on or contracting installation services for PV systems should be familiar with standards established by the Occupational Safety and Health Administration (OSHA), contained in Volume 29 of the U.S. Code of Federal Regulations (29 CFR).
OSHA regulations are applicable in all U.S. states and territories and enforced by federal or local authorities. States with OSHA-approved programs must set standards at least as effective as federal standards. These standards apply to private employers and general industry, construction, maritime, agricultural and other occupations. The broad scope of OSHA regulations includes health standards, electrical safety, fall protection systems, stairways and ladders, hand and power tools, cranes and lifts, excavations, scaffolding, and other potential hazards likely to be encountered in construction practice and many PV installations.
OSHA regulations require that employers provide a safe and healthful workplace free of hazards, and follow the applicable OSHA standards. Employers must provide training, and employers of 11 or more employees must maintain records of occupational injuries and illnesses. All employers must display the OSHA poster, and report to OSHA within 8 hours any accident that results in a fatality or in-patient hospitalization of 3 or more employees.
Workers are responsible for following the employer’s safety and health rules and wear or use all required gear and equipment, reporting hazardous conditions to OSHA if employers do not fix them, and cooperating with OSHA inspectors. Large construction projects often require workers to complete 10 or 30 hour training on OSHA regulations and have a valid course completion card for insurance purposes.
Specifically, 29 CFR Part 1926 Safety and Health Regulations for Construction applies to general construction practice, including several subparts applicable to the installation of PV systems
Subpart D – Occupational Health and Environmental Controls
Subpart E – Personal Protective and Life Saving Equipment
Subpart I – Tools, Hand and Power
Subpart K – Electrical
Subpart X – Stairways and Ladders
- No Construction worker will be required to perform work under safe conditions that are unsanitary, hazardous, or dangerous to his safety or health.
- The employer shall initiate and maintain a job site safety and health program.
- The use of any machinery, tool, material, or equipment that is not in compliance with safety standards is prohibited
- Every employee shall be instructed in the recognition and avoidance of unsafe conditions.
- Every employee shall be instructed in the safety and health regulations applicable to his/her work.
