Focus On Things Your Are Good At- The first step to choosing a good idea for a process essay is to think of a process that you understand better than other students in your class.

Exposure to the potential hazards listed in table Historically, industrial pulp and paper production was a semi-automatic process which required a great deal soaps writing analysis paper manual intervention.

In such facilities, operators would sit at open panels adjacent to the processes to view the effects of their actions. The valves at the top and bottom of a batch digester would be manually opened, and during the filling stages, gases in the digester would be displaced by the incoming chips figure Chemical levels would be adjusted based on experience rather than sampling, and process adjustments would be dependent on the skill and knowledge of the operator, which at times led to upsets.

For example, over-chlorination of pulp would expose workers downstream to increased levels of bleaching agents. In most modern mills, progress from manually controlled to electronically controlled pumps and valves allows for remote operation.

The demand for process control within narrow tolerances has required computers and sophisticated engineering strategies.

Separate control rooms are used to isolate the electronic equipment from the pulp and paper production environment. Consequently, operators usually work in air-conditioned control rooms which offer refuge from the noise, vibration, temperature, humidity and chemical exposures inherent to mill operations.

Other controls which have improved the working environment are described below. Guards around moving conveyors and machinery parts, quick clean-up of spills, walking surfaces which allow drainage, and guard-rails on walkways adjacent to production lines or at height are all essential.

Lock-out procedures must be followed for maintenance of chip conveyors, paper machine rolls and all other machinery with moving parts.

Mobile equipment used in chip storage, dock and shipping areas, warehousing and other operations should have roll-over protection, good visibility and horns; traffic lanes for vehicles and pedestrians should be clearly marked and signed. Noise and heat are also ubiquitous hazards.

The major engineering control is operator enclosures, as described above, usually available in wood preparation, pulping, bleaching and sheet-forming areas. Air-conditioned enclosed cabs for mobile equipment used in chip pile and other yard operations are also available.

Outside these enclosures, workers usually require hearing protection.

Work in hot process or outdoor areas and in vessel maintenance operations requires workers to be trained to recognize symptoms of heat stress; in such areas, work scheduling should allow acclimatization and rest periods.

Cold weather may create frostbite hazards in outdoor jobs, as well as foggy conditions near chip piles, which remain warm. Wood, its extracts and associated micro-organisms are specific to wood preparation operations and the initial stages of pulping.

Control of exposures will depend on the particular operation, and may include operator booths, enclosure and ventilation of saws and conveyors, as well as enclosed chip storage and low chip inventory.

Use of compressed air to clear wood dust creates high exposures and should be avoided. Chemical pulping operations present the opportunity for exposures to digestion chemicals as well as gaseous by-products of the cooking process, including reduced kraft pulping and oxidized sulphite pulping sulphur compounds and volatile organics.

Gas formation may be influenced by a number of operating conditions: Operators taking samples and conducting tests should be aware of the potential for acid and caustic exposure in process and waste streams, and the possibility of side reactions such as hydrogen sulphide gas H2S production if black liquor from kraft pulping comes into contact with acids e.

Job responsibilities may require workers to come into direct contact with these chemicals, making heavy duty clothing a necessity. For example, workers rake the spattering molten smelt that collects at the base of the boilers, thereby risking chemical and thermal burns.

Workers may be exposed to dust when sodium sulphate is added to concentrated black liquor, and any leak or opening will release noxious and potentially fatal reduced sulphur gases. The potential for a smelt water explosion always exists around the recovery boiler. Water leaks in the tube walls of the boiler have resulted in several fatal explosions.

Recovery boilers should be shut down at any indication of a leak, and special procedures should be implemented for transferring the smelt.HOW TO WRITE: AP Rhetorical Analysis Paragraphs and Essays Things you must know in order to accurately analyze a text: 1.
