Daily Worker

The workforce consists of 92 shift and 8 daily workers. Approximately 20 to 30 different fine chemicals are produced per year which range ia volume from 20 to 200 metric tons per train and ia campaign length from 20 to 180 days. 

Change Daily Workers whose clothing may have become contaminated should change into uncontaminated clothing before leaving the work premises. 

Short-term exposure. This is the maximum concentration to which workers can be exposed for a period of up to 15 minutes continuously without suffering from (a) intolerable irritation, (b) chronic or irreversible tissue change, or (c) narcosis of sufficient degree to increase accident proneness, impair self-rescue, or materially reduce efficiency, provided that no more than four excursions per day are permitted, with at least 60 minutes between exposure periods, and provided the daily time-weighted value is not exceeded. 

If possible comparisons are focused on energy systems, nuclear power safety is also estimated to be superior to all electricity generation methods except for natural gas (30). Figure 3 is a plot of that comparison in terms of estimated total deaths to workers and the pubHc and includes deaths associated with secondary processes in the entire fuel cycle. The poorer safety record of the alternatives to nuclear power can be attributed to fataUties in transportation, where comparatively enormous amounts of fossil fuel transport are involved. Continuous or daily refueling of fossil fuel plants is required as compared to refueling a nuclear plant from a few tmckloads only once over a period of one to two years. This disadvantage appHes to solar and wind as well because of the necessary assumption that their backup power in periods of no or Httie wind or sun is from fossil-fuel generation. Now death or serious injury has resulted from radiation exposure from commercial nuclear power plants in the United States (31). 

Short-term exposure limit (STEL) TLV - the eoneentration to whieh it is believed that workers ean be exposed eontinuously for a short period of time without suffering from initation, ehronie or irreversible tissue damage, or nareosis of suffieient degree to inerease the likelihood of aeeidental injury, impair self-reseue or materially reduee work effieieney, and provided that the daily TWA limit is not exeeeded. A STEL is a 15 min TWA exposure whieh should not be exeeeded at any time during the work day even if the TWA is within the TLV. It should not oeeur more than four times per day or without at least one hour between sueeessive exposures. 

Health and safety planning and implementation emphasize jobs and tasks. Many DOE or Army Corps of Engineers sites have an established work control system (WCS) that is focused at the job and task level. Workers are familiar with the WCS and understand its content because each work-task package includes checklists and permits. This is a normal part of daily work. The WCS is a practical vehicle for managing and conducting these activities and supports the HASP by providing a mechanism to accomplish the following ... 

The safety alert concept is another tool that can be used by large or small businesses to communicate past best practices and indicate a path forward. On a daily basis, lessons learned should be communicated in a site safety meeting. A worker or supervisor may have discovered that a current practice could cause a potentially dangerous situation. Many times the correction or long-term fix for a hazard involves engineering... 

The hazardous waste standard requires employers to make certain that when showers are a necessary step in the decontamination process, their employees shower at the end of their work shift and when leaving the hazardous waste site. Sanitation-related showers (unlike decontamination showers) are understood to be voluntary. Decontamination and emergency showers should be located close to the worksite. Sanitary showers may be located at some distance from the worksite. A statement in the safety plan encouraging good personal hygiene and daily showers is a good idea. In addition, workers should be encouraged to shower daily even if no shower is available at the worksite. 

Daily work procedure characterization for each worker must be outlined early in the design process. 

TTie ability of the ventilation system to protect the worker efficiently can readily be determined by personal samples. The PIMEX method (see Chapter 12) can be used to determine the worker s exposure during various work phases. The capture efficiency as well as the supply air fraction can be measured using tracer gas techniques. Simple evaluation is carried out visually with smoke tube or pellet tests. Daily system evaluation is recommended using airflow or static pressure measurements at appropriate parts of the system. The air velocities, turbulence intensities, air temperature, mean radiant temperature, and air humidity should also be measured to provide an assessment ol thermal comfort. 

You liave been hired as a consultant to a company administrator who has a limited budget for die mitigation of hazards in a certain chemical plant. The plant employs two kinds of workers day employees tliat work one 8 hour sliLft daily, and sliift employees that rotate tlirougli tliree 8 hour shifts each day. A HAZOP-HAZAN report reveals two kinds of accidents are possible during plant operation. 

Short-Term Exposure Limit (STEL)—The American Conference of Governmental Industrial Hygienists (ACGIH) maximum concentration to which workers can be exposed for up to 15 min continually. No more than four excursions are allowed per day, and there must be at least 60 min between exposure periods. The daily Threshold Limit Value - Time Weighted Average (TLV-TWA) may not be exceeded.
