Water Works Safety

This section provides a brief listing of regulatory federal and provincial legislation that governs safety issues in Canada and the websites where these regulations can be obtained. Also in this section is a list of websites for mandatory documents that every private and municipal water operation should have access to, with preference of a hard copy at each facility. The web links will require some independent research to assess the importance of each topic as it applies to specific Canadian jurisdictions. 

Websites are listed for federal and provincial legislation and acts and the web links— current as of the publication of this manual—to access these documents are provided. Note that the judicial system in Canada is at the top of the hierarchy for final approval, watch guarding, and enforcing safety regulations and standards. 

This list serves as an introduction to assist Canadian water works safety officers, joint safety committees, and management in quickly obtaining safety information for starting a safety program and for continuing current information on safety topics as they pertain to water works operations.

In states with their own programs (see www.osha.gov/dcsp/osp/index.html) utility managers should review the state requirements, as sometimes they differ from OSHA requirements. For Canadian utilities, the links listed in the appendix, Canadian Water Works Safety References, should be used. Also, consider contacting AWWA Section Safety Committees to inquire how others are addressing various hazards.

There are many reasons for testing water, including compliance testing, process quality control, safety and health. There is one definitive source of water testing methods and that is Standard Methods for the Examination of Water and Wastewater, a joint publication of the American Public Health Association, The American Water Works Association, and the Water Pollution Control Federation... 

Notes (1) You should work as part of a team of two to four analysts to discover the properties in Part A, but work on your own to analyze the unknowns in Part B. (2) Whenever you are directed to shake a test tube, wear latex gloves and place your finger over the mouth of the tube and then shake the tube. Before proceeding to the next test tube, rinse your latex-covered finger with distilled water to avoid cross-contamination. (3) See the Suggested format for lab notebook at the end of the procedure. (4) Use distilled water whenever the procedure calls for water. Reminder Safety glasses are required and latex gloves should be worn. 

The American Water Works Association is pleased to provide you with this 2011 edition of Let s Talk Safety. We ve reviewed, updated, and edited the discussion topics to ensure they continue to be current, pertinent, and beneficial to you and your employees. For example, this edition provides updated information about the revised cardiopulmonary resuscitation (CPR) guidelines recently adopted by the American Heart Association. There s also an important overview of the much-anticipated revisions to Occupational Safety and Health Administration (OSHA) regulations on cranes and derricks. New articles provide helpful tips on preventing heat illness and guidelines for ensuring the safety of employees working in remote locations. We ve added Web site addresses to every article so you and your staff can conduct deeper research into particular safety topics.

Reppe s work also resulted in the high pressure route which was estabUshed by BASF at Ludwigshafen in 1956. In this process, acetylene, carbon monoxide, water, and a nickel catalyst react at about 200°C and 13.9 MPa (2016 psi) to give acryUc acid. Safety problems caused by handling of acetylene are alleviated by the use of tetrahydrofuran as an inert solvent. In this process, the catalyst is a mixture of nickel bromide with a cupric bromide promotor. The hquid reactor effluent is degassed and extracted. The acryUc acid is obtained by distillation of the extract and subsequendy esterified to the desked acryhc ester. The BASF process gives acryhc acid, whereas the Rohm and Haas process provides the esters dkecdy. 

Appropriate protective clothing and equipment should be worn to minimize exposure to methacrylate liquids and vapors. Chemically resistant clothes and gloves and splash-proof safety goggles ate recommended. The working area should be adequately ventilated to limit vapors. Should chemical exposure occur, contaminated clothing should be removed and the affected area washed with copious amounts of water. Medical attention should be sought if symptoms appear. Eurther information about methyl methacrylate and other methacrylates is available (141). 

The isolation of certain mechanical equipment, e.g. conveyors, work on lifts, excavations, entry and positioning of cranes, isolation of various safety services , e.g. water or inert gas, stand-by power generation, water supply to sprinkler systems, compressed air for breathing apparatus. 

Worker eomfort areas ean be loeated in site work zones. These eomfort zones allow workers to take breaks and rest without being eontaminated. These areas are designed to maintain the safety of workers and generally require speeial proeedures for ingress and egress, personnel and air monitoring, potable water eonsumption, and restroom use [1],...
