An effective SDS and hazardous-substance safety program should ensure that every hazardous chemical is identified, assessed, and controlled before work begins. In practice, this means maintaining accessible Safety Data Sheets, using them to identify chemical hazards and required precautions, and conducting a documented workplace hazard assessment to determine what controls and PPE are needed. The source documents emphasize that employers must assess workplace hazards, document the assessment, and use that process to select protective measures. [4] [13] [1]

Key elements for hazardous substance identification and SDS management:

• Keep a current SDS for each hazardous substance used, stored, or generated in the workplace, and make sure employees can access it during their work shift.
• Verify that each chemical container is clearly identified and matched to the correct SDS so workers can confirm hazards such as flammability, corrosivity, toxicity, sensitization, reactivity, and required first-aid measures.
• Use the SDS together with a workplace walk-through and job/task review to identify where exposures may occur, who may be affected, and what controls are required.
• Review and update hazard assessments whenever jobs change, new equipment or processes are introduced, after an accident, or at least periodically.

[10] [7] [15] For handling and storage, hazardous substances should be managed according to the SDS and the specific risks identified in the hazard assessment. Safe handling normally includes minimizing contact, preventing splashes and releases, using only trained personnel, and applying engineering, work-practice, and administrative controls before relying on PPE. Safe storage generally includes keeping chemicals in compatible containers, segregating incompatibles, controlling ignition sources where applicable, maintaining good housekeeping, and ensuring damaged protective equipment is replaced promptly. [5] [6] [11]

Exposure controls and personal protective equipment:

• Apply the hierarchy of controls first: eliminate the hazard where possible, then use engineering controls, work-practice controls, and administrative controls before PPE.
• Select PPE that matches the specific hazard and task, and provide properly fitting equipment to each affected employee.
• Train employees on PPE selection, use, care, limitations, and replacement, and document that training.
• For chemical work, choose gloves based on the SDS and the chemical hazard; replace gloves or other PPE that are damaged, defective, or worn.
• Where respiratory hazards exist, implement a written respiratory protection program, conduct medical evaluations and fit testing, perform air monitoring as needed, and keep records on file.
• Use eye/face, head, foot, hand, body, hearing, or fall protection as indicated by the hazard assessment and the task being performed.

[2] [6] [2] [1] [3] [8] Emergency response procedures for hazardous substances should be written, trained, and aligned with the SDS. At minimum, workers should know how to report a spill or exposure, isolate the area, use emergency eyewash/shower or first aid as appropriate, obtain medical assistance, and use only the spill-response equipment and PPE for which they are trained. Emergency arrangements should also address fire or explosion hazards, evacuation, incident reporting, and post-incident review so controls can be improved.

For regulatory compliance and workplace safety documentation, employers should maintain a documented hazard assessment, PPE selection records, training records, inspection and maintenance records, respiratory program records where applicable, and written safety policies integrated into the broader workplace safety program. The documents also show that hazard-assessment certification should identify the workplace, the person certifying the assessment, and the date. Written programs should define responsibilities, hazard assessment procedures, PPE selection, training, and cleaning/maintenance requirements. [15] [12] [14] [9]

Recommended workplace documentation set:

• Chemical inventory linked to current SDSs
• Hazard communication procedures, including labeling and employee access to SDSs
• Hazard assessment and certification forms for tasks, areas, and substances
• PPE hazard assessments, selection decisions, and issue records
• Employee training records, sign-in sheets, quizzes, and certifications
• Respiratory protection program, medical evaluations, fit tests, and air monitoring records where required
• Inspection, maintenance, and replacement records for PPE and emergency equipment
• Incident, spill, exposure, and corrective-action reports
• Written emergency response and evacuation procedures
• Periodic program review records showing updates and effectiveness evaluations
