SMALL SYSTEMS MAINTENANCE FOR WATER TREATMENT 6 Notes 11/03 03/03 6-16
SMALL SYSTEMS MAINTENANCE PROCEDURES FOR A MODIFIED LANDFILL 7 7.0 SAFETY FOR WATER TREATMENT 7.1 OBJECTIVES The trainee will be able to: 1. Name three personal hazards common to treatment plants. 2. Recall the safety measures to follow when working in or around: a) Wet Wells b) Chlorine Buildings c) The Laboratory d) <strong>Plant</strong> and equipment during servicing. 7.2 INTRODUCTION The dangers associated with plant operations emphasize the need for safety practices. Physical injuries and body infections are a continuous threat and occur with regularity. Explosions and asphyxiation from gases or oxygen deficiency do occur. Although rare in the North, country-wide such accidents happen daily. <strong>Water</strong> treatment plant occupational hazards may be largely avoided by following safe practices and the use of safety equipment. The dangers are many and carelessness happens all too frequently until an accident happens. Then it is too late. It is the responsibility of supervisors to get to know the hazards associated with plant maintenance and operation and to take steps to avoid them. Accident prevention is the result of thoughtfulness and the application of a few basic principles and knowledge of the hazards involved. It has been said that the ABC of accident prevention is "Always Be Careful". One must learn how to be careful and what to avoid. 7.3 WORKERS’ COMPENSATION BOARD With safety, the ultimate requirements and regulations come from the Workers’ Compensation Board (WCB) of the Northwest Territories and Nunavut. Know the regulations as applicable to your job and employ them in your everyday work. The WCB maintains a vast library of Operational Health and Safety manuals, which are at your 11/03 03/03 7-1
