What information must be provided and exchanged between employers, employees and outside undertakings regarding risks and dangerous substances?

• A. Maintenance
• B. Training
• C. Provision of Information to Employees and the Self-Employed from Outside Undertakings
• D. Emergency Routes and Exits

Answer: (C)

Exchange of information about risks and dangerous substances between employers, employees, and outside undertakings is required to ensure everyone on site knows what hazards exist, what controls are in place, and what to do in an emergency. When dangerous substances are present or when outside workers (contractors, suppliers) come onto the premises, there needs to be clear provision of relevant information to employees and, in turn, information about site hazards and procedures from those outside undertakings back to the employer and their workers. This coordinated flow allows safe systems of work, proper planning, and timely communication of any changes in substances or procedures.

Other options point to actions or features that don’t directly address sharing hazard information: maintenance deals with equipment upkeep, training is general education, and emergency routes and exits are physical safety arrangements rather than information exchange about risks.
