While the documents provided are specific to Oregon's hazard communication regulations, the general principles of hazard communication are applicable across the United States, including Maine, due to the federal OSHA standards. Here are some key points to consider for hazard communication in the workplace:

1. Safety Data Sheets (SDS): Employers must maintain copies of safety data sheets for each hazardous chemical used in the workplace. These should be readily accessible to employees during each work shift. Electronic access is permissible as long as it does not create barriers to immediate access [1].

2. Labeling: All containers of hazardous chemicals must be labeled with the appropriate hazard information. This includes product identifiers, signal words, hazard statements, pictograms, and precautionary statements [2].

3. Employee Training: Employers are required to provide effective information and training on hazardous chemicals at the time of an employee's initial assignment and whenever a new chemical hazard is introduced. Training should cover detection methods, physical and health hazards, protective measures, and details of the hazard communication program [3].

4. Written Hazard Communication Program: Employers must develop, implement, and maintain a written hazard communication program. This program should describe how labeling, safety data sheets, and employee training requirements will be met [4].

5. Multi-Employer Workplaces: If employees of other employers may be exposed to hazardous chemicals, the primary employer must ensure that the hazard communication program includes methods to provide access to safety data sheets and inform other employers of necessary precautionary measures [2].

For specific regulations in Maine, it is advisable to consult the Maine Department of Labor or OSHA's regional office for guidance tailored to state-specific requirements.
