It provides guidance for process and job evaluation with suggestions based upon typical potential hazards for farm digester systems and their associated preventive measures. Nellie J. Brown http://works.bepress.com/nellie_brown/18 http://works.bepress.com/nellie_brown/18 Tue, 20 May 2008 09:41:59 PDT [Excerpt] Firefighters, as well as victims, can be exposed to a variety of toxic substances during a fire. Some of these toxicants are particularly insidious because they are produced by thermal decomposition before smoke makes a fire evident. Nellie J. Brown http://works.bepress.com/nellie_brown/17 http://works.bepress.com/nellie_brown/17 Fri, 14 Mar 2008 06:38:18 PDT Once an employer learns an applicant or employee is allergic, and in need of an accommodation, the employer may be required by the Americans with Disabilities Act to provide the needed accommodation. The allergic worker may be able to respond to low levels of exposure, levels which may be lower than the relevant occupational exposure limits set by OSHA or recommended by agencies such as NIOSH or organizations such as the ACGIH. Accommodating the allergic employee would therefore generally involve reducing exposure further by providing specific protection for the sensitive individual, such as additional protective equipment which the average (nonallergic) worker probably wouldn't need. Protective equipment could involve the use of respirators for respiratory protection or protective clothing (such as gloves) or barrier creams for skin protection. The use of respirators would involve employer compliance with OSHA's Respiratory Protection Standard (29 CFR 1910.134) including the use of a physical to determine whether a worker could wear a respirator. Battery-powered respirators may enable those with pulmonary or cardiovascular problems to still use a respirator. Respirators made of silicone may enable someone to wear a respirator who has a rubber allergy (such as an allergy to mercaptobenzothiazole). Nellie J.

It was adapted from basic elements of both traditional job hazard analysis and process hazards analysis (particularly hazard and operability analysis) techniques, and is intended to overcome some of the limitations of both methods for someone conducting a site walk-through consisting of less than one day of available time.

Brown Waste Management http://works.bepress.com/nellie_brown/15 http://works.bepress.com/nellie_brown/15 Fri, 14 Mar 2008 06:28:31 PDT [Excerpt] A composting project in a school, either in the classroom or on the school property, can be a terrific opportunity for students to gain direct knowledge and experience with natural processes and a method of reducing and recycling biodegradable wastes. Although composting utilizes natural decay processes, these processes are occurring in a relatively small, concentrated area of a pile or bin. There is a potential for human exposure to the organisms involved and the products they produce. Nellie J. Brown Waste Management http://works.bepress.com/nellie_brown/14 http://works.bepress.com/nellie_brown/14 Fri, 14 Mar 2008 06:28:25 PDT [Excerpt] The metalworker can be exposed to cutting oils during application by two basic routes of entry: skin contact and inhalation. The higher risk jobs tend to be those with high cutting speeds, heavy oil flow, and continuous contact, which may result in the worker being splashed with oil on the skin or clothing. The oil may remain on the skin for some time and oil-soaked clothing may be worn all shift.Cutting oils may be applied manually, by an air-carried mist, or by a continuous flood. When flooding is used, the oil is delivered by a pump, piping, and nozzle to the cutting zone. With this method the tool, work, and chip are flooded. (Used fluid is then collected in the chip pan and returned by gravity to the pump sump.)Inhalation of cutting oil mists may occur because of the nature of coolant delivery or because of the high temperatures and speeds generated at the cutting tool's working edge. When the mist stream method of coolant delivery is used, much of it evaporates on contact with the hot tool, workpiece or chip. In addition to the intentional production of oil mists, vaporized oil can also be generated by the forces of the rapidly spinning workpiece or tool, or by the vaporization of the fluid from the heat of the cutting process.
