1. Maintenance Safety

2. Maintenance Problems n Operative usually works in dangerous areas from which others are usually excluded by various safety barriers n Emergency repairs are particularly dangerous because work is usually performed under stress, with the offending plant still hot, cold or stuck in some phase of its operating cycle

3. Maintenance Problems n No safe system developed or used n No means of isolation to lock-off plant and machinery or power supplies n Lack of understanding of risks by maintenance workers n Lack of training and lack of supervision

4. Maintenance Hazards n Confined spaces e.g. vessels, tanks, pipework, chambers, machines n Work on tanks, pipes or vessels which may contain a hazardous substance e.g. hot cutting or welding a silo containing explosive dust n Construction/demolition of structures and work at heights e.g. use of scaffolding and access platforms, excavations, roof maintenance, work on overhead cranes

5. Maintenance Hazards n Work on plant, machinery or equipment which is connected to a power source n Work in plant, boilers, silos etc where entry of free- flowing solids or liquids is a possibility e.g. water, grain etc. n Work in plant where entry of toxic or hazardous materials is a possibility e.g. carbon monoxide, methane etc. n Asbestos is frequently encountered in maintenance operations
