Project No.4-419-0381 <br /> August 29,2019 <br /> Page No.22 <br /> their employer. This standard practice instruction establishes uniform requirements to ensure that <br /> procedures to limit the spread of such hazards are implemented, evaluated, and that the proper hazard <br /> information is transmitted to all affected workers. <br /> Engineering and work practice controls shall be used to eliminate or minimize employee exposure. Where <br /> occupational exposure remains after institution of these controls,personal protective equipment shall also <br /> be used.Engineering controls shall be examined and maintained or replaced on a regular schedule to ensure <br /> their effectiveness. This schedule will be posted and documented. <br /> SALEM will provide hand-washing facilities that are readily accessible to employees. When provision of <br /> hand-washing facilities is not feasible, this employer shall provide an appropriate hand cleanser in <br /> conjunction with clean cloth/paper towels or antiseptic towelette. When antiseptic cleansers or towelette <br /> are used, hands shall be washed with soap and running water as soon as feasible. Also, employees shall <br /> wash their hands immediately or as soon as feasible after removal of gloves or other personal protective <br /> equipment. Employees will wash their hands and any other skin with soap and water, or flush mucous <br /> membranes with water immediately or as soon as feasible following contact of such body areas with blood <br /> or other potentially infectious materials. <br /> 3.3.8.10 Spiders <br /> Only a few spiders are dangerous to humans. The black widow (Lactrodectus mactans) is known for the <br /> red hour glass marking on its underside. <br /> Spiders prefer warmer climates and dark dry places where flies are plentiful. For these reasons,they often <br /> live in outdoor toilets. If possible, it is best to capture the spider for identification. <br /> Bites from spiders may feel like a pinprick and may not even be noticed,but within hours, swelling at the <br /> site and breathing problems may occur. Emergency help should be immediately sought.A cloth dampened <br /> with cold water or filled with ice may be applied to the bite while awaiting help. <br /> 3.4 Dust Hazards <br /> During site activities, engineering and administrative controls will be implemented to minimize the levels <br /> of airborne dusts in the atmosphere. Airborne dusts can be reduced by suppression, dilution, and on site <br /> work practices. The extent of site dust emissions will be controlled and monitored in order to comply with <br /> the Air Quality Management District rules. The subcontractor should take every reasonable precaution to <br /> minimize emissions during all field activities. <br /> During site activities the work area should be kept damp to minimize airborne concentrations of dust. If <br /> water is used for dust control it may be mixed with a dust-allaying agent or hygroscopic salt to reduce the <br /> amount of evaporation.Water usage shall not result in creating mud,run off, or ponding water. <br /> When high dust levels are present employees should wear MSHA/OSHA approved respirators with HEPA <br /> filters. Inhaled dust may cause irritation of the nose and throat. Respiratory irritation may be experienced <br /> as coughing, difficulty in breathing, and/or nasal discharge. Overexposure to dust may aggravate existing <br /> respiratory conditions such as asthma,bronchitis, and inflammatory or fiber optic respirator disease. <br /> 3.5 Personal Hygiene <br /> Field team personnel should conduct the following to ensure that contaminants will not remain in contact <br /> with their bodies: <br /> SALEM <br /> engineering group. inc. <br />
