Final answer:
Licensed cosmetology service providers must provide Material Safety Data Sheets (MSDS) or Safety Data Sheets (SDS) for all salon chemicals as per OSHA guidelines to ensure a safe working environment.
Step-by-step explanation:
All licensed cosmetology service providers must provide Material Safety Data Sheets (MSDS) or Safety Data Sheets (SDS) for all chemicals used in the salon. These documents provide detailed information on the properties of each chemical, including its potential hazards and instructions for safe handling, storage, and disposal. Following the guidelines outlined by the Occupational Safety and Health Administration (OSHA), it's essential to inform workers about chemical hazards properly to ensure a safe working environment. This can include training, labels, alarms, color-coded systems, and other methods. Employers are also responsible for making feasible changes in working conditions to reduce or eliminate hazards before relying on personal protective equipment.
