Higher learning: Safety training in cannabis industry a growing concern
With marijuana legal in nearly half of the U.S., the cannabis industry – which includes growing, harvesting, processing, and retail – has grown exponentially, grossing nearly $34 billion in 2023. Recreational marijuana is legal in 24 states, and medical marijuana is legal in 37. Throughout the country, more than 430,000 people are working in the industry; in Michigan alone, there are over 1,000 growers, 228 processors, and 1,040 dispensaries.
State regulations and training
In states where cannabis operations are legal, regulations are often scattered among various agencies, making both compliance and enforcement a challenge. Be sure to check the applicable safety and health regulations to determine what’s required in your state. For example, in Nevada, OSHA 10- and 30-hour training is required for employees of cannabis establishments. The state statutes define “cannabis establishment” to mean “an adult-use cannabis establishment or a medical cannabis establishment.” Keep in mind that while OSHA 10- and 30-hour training provides a general overview of common workplace hazards, workplace-specific training also must be provided.
What are the hazards?
In Washington state, safety officials most often issue citations for program violations, confined spaces, and chemical hazards, and a Massachusetts cannabis industry worker’s death in 2022 sparked concerns about biological occupational exposures. However, there are numerous other hazards involved in growing, harvesting, processing, and retail. Let’s take a look at some of these hazards and where training should be implemented.
Activity or hazard | Training |
Trimming with hand tools, bending, stooping, carrying large potted plants | Ergonomics – General Duty Clause or state requirements, if applicable |
UV rays from grow lights | PPE – Eye and face protection, 1910.133 Note: Eye protection must be wavelength specific based on the type of UV light in use. Regular sunglasses do not offer sufficient protection. |
Chemicals, i.e., cleaning agents, pesticides, carbon dioxide, THC from plant oil | Hazard communication, 1910.1200 Note: Employers must have a Safety Data Sheet (SDS) for each hazardous chemical that they use. Growers and processors of cannabis products must develop or obtain an SDS for cannabis products such as ground cannabis flower and extracted cannabis oils. |
Chemical storage | Flammable liquids, 1910.106 Hazard communication, 1910.1200 |
Noise from growing and processing equipment | Occupational noise exposure, 1910.95 |
Heat and humidity | Heat stress – General Duty Clause or state requirements, if applicable |
Workplace violence related to asset protection | Workplace violence – General Duty Clause or state requirements, if applicable |
Cutting hazards, trimming equipment | Machine guarding, 1910.212 |
Use of forklifts, pallet jacks, etc. | Powered industrial trucks (PITs), 1910.178 |
Use of ladders, fall protection, etc. | Walking- working surfaces, 1910.30 |
Use of compressed air | Compressed gases and compressed air equipment, 1910.169 |
Working in confined spaces | Permit-required confined spaces, 1910.146 |
Cleaning high-contact surfaces and eating/drinking areas to reduce exposure | Sanitation, 1910.141 |
