Protection Requirements

ESD system components that are located in areas that would be considered direct fire exposures, i.e. within or above fire hazardous risk areas should be provided fire protection measures to ensure integrity during ESD operation and the duration of the major efforts to control the emergency. 

Valve Actuating Mechanisms 15-20 minutes H rating (HI 5 or H20, plus blast if applicable) 

Actuating mechanisms include control panels, air receivers, valve actuators, instrumentation controls or tubing, etc.

Low Level Waste. The NRC 10CFR61 specifies the nature of the protection required for waste containers (20). Class A wastes must meet minimum standards, including no use of cardboard, wastes must be solidified, have less than 1% Hquid, and not be combustible, corrosive, or explosive. Class B wastes must meet the minimum standards but also have stabiHty, ie, these must retain size and shape under soil weight, and not be influenced by moisture or radiation. Class C wastes must be isolated from a potential inadvertent intmder, ie, one who uses unrestricted land for a home or farm. Institutional control of a disposal faciHty for 100 years after closure is requited. 

Enameling meets decorative as weU as protective requirements. Ceramic enamels are mainly based on alkaH borosiHcate glasses. The part to be enameled is dipped into or sprayed with a sHp, ie, a water suspension of glass fragments called frit. The sHp coating is dried and fused in an enameling furnace under careful heat control (see Enamels, porcelain or vitreous). 

Vaulted. Vaulted tanks are installed inside a concrete vault. The vault, itself a Hquid-tight compartment, reduces the fire protection requirements as the NFPA and the International Fire Code Institute (IFCI) recognize these tanks as fire-resistant aboveground storage tanks. The vault provides a two-hour fire wall, thermal protection that minimizes tank breathing losses and pollution, secondary containment, and baUistic protection. 

The coating thickness may range from 0.0025 to 0.05 mm, depending on the type of protection required. Pure tin coatings are used on food-processing equipment, milk cans, kitchen implements, electronic and electrical components, fasteners, steel and copper wire, pins, automotive bearings, and pistons. 

Detection of Bromine Vapor. Bromine vapor in air can be monitored by using an oxidant monitor instmment that sounds an alarm when a certain level is reached. An oxidant monitor operates on an amperometric principle. The bromine oxidizes potassium iodide in solution, producing an electrical output by depolarizing one sensor electrode. Detector tubes, usefiil for determining the level of respiratory protection required, contain (9-toluidine that produces a yellow-orange stain when reacted with bromine. These tubes and sample pumps are available through safety supply companies (54). The usefiil concentration range is 0.2—30 ppm. 

Zinc—Iron. The Zn—Ee aHoy is plated from an alkaline bath. Deposits are 0.3—0.8% iron and can be given attractive, resistant, black, sHver-free chromate coatings. Corrosion protection requires the heavier, darker chromates. Zinc—iron baths are the most economical of the 2inc aHoys.

If the oxygen content of the contaminated air is deficient (refer to page 72), breathing apparatus is essential. The degree of protection required is determined by the level of contamination, the hygiene standard for the contaminant(s), the efficiency of any filter or adsorber available, and the efficiency with which the facepiece of the device seals to the user s face (this is reduced by beards, spectacles etc.). The level of comfort and user acceptability are further considerations.

Non-RCRA-permitted TSDs and waste treatment activities not covered by RCRA (e.g., wastewater treatment facilities permitted under the Clean Water Act) are not covered by HAZWOPER, except for emergency response and some limited waste management operations. Specific HAZWOPER elements are assimilated into the existing health and safety program based on hazard analyses. Worker protection requirements are met through existing health and safety plans [1]. 

We should keep in mind that the main difference between level D and C equipment is the amount of respiratory protection. Level C protection requires use of a respiratory device (APR). Requiring workers to work in level C for more than a small percentage of the time can prove to be a challenging situation for both workers and managers. Respirators, especially full-face respirators, can provide excellent protection for workers, but are also found to be a source for worker complaints. 

Medically evaluating, training, qualifying, and fit-testing workers for specific respirator types, checking 29 CFR 1910, Subpart Z, Toxic and Hazardous Substances, for any special respiratory protection requirements (e.g., for asbestos, lead, or cadmium) [3]... 

The employer issues a hot work permit for hot work operations conducted on or near a covered process. The permit documents that the fire prevention and protection requirements in 29 CFR 1910.252(a) have been implemented prior to beginning the hot work operations it indicates the date(s) authorized for hot work and identifies the object on which hot work is performed. The permit is kept on file until completion of the hot work operations. 

One method that can be used to overcome most of the environment-induced problems is to use plastic tubing to shield the beam. This tubing can be placed between the transmitter and receiver of the optical-alignment fixture. It should be sized to permit transmission and reception of the light beam, but small enough to prevent distortion caused by atmospheric or environmental conditions. Typically, 2-inch, thin-wall tubing provides the protection required for most applications. 

Aluminium is widely applied for decorative and protective requirements, while cadmium , zinc and titanium have been applied to ferrous materials chiefly for their protective value. The method finds particular application in the plating of high-tensile steels used in aviation and rocketry, car fittings and lamp reflectors, and gramophone record master discs, as well as in the preparation of specimens for electron microscopy and in rendering insulated surfaces electrically conducting, e.g. metallising of capacitors and resistors. 

One of the conclusions from the 1992 United Nations Conference on Environment and Development in Rio de Janeiro (the Earth Summit) was the urgent need to find a more sustainable way of life, based on careful use of resources and a reduction in environmental emissions. There was also a call to move towards a model in which environmental enhancement is fully integrated with economic development. The consequences of this summit have been far-reaching not least by the fact that, in Europe and elsewhere, environmental protection requirements are now integrated into many policies rather than being separate pieces of legislation. Indeed Article 2 of the EC treaty states that the Community shall. .. promote throughout the Community harmonious, balanced and sustainable development of economic activities This may be viewed as the first step towards... 

Effective protection requires at the very least reimbursement for innovators development costs, that is, the costs of producing an original innovation which are not incurred again when the innovator produces new units, and which competitors will not incur even in the first unit they produce. An optimal protection system should offer additional incentives. It should compensate not only development costs but also the risk involved in innovating, and it should internalize society s preferences for certain types of good. Society values some innovations more than others, and thus reward merely for the risk involved in innovating would be insufficient. The size of this additional...
