Suits, safety

The comprehensive and detailed assessment of the risks required for a safety-case can only be satisfactorily carried out for major installations with the aid of computer software. Suites of programmes for quantitative risk analysis have been developed over the past decade by consulting firms specializing in safety and environmental protection. Typical of the software available is the SAFETI (Suite for Assessment of Flammability Explosion and Toxic Impact) suite of programs developed by DNV Technica Ltd. These programs were initially developed for the authorities in the Netherlands, as a response to the Seveso Directives of the EU (which requires the development of safety cases and hazard reviews). The programs have subsequently been developed further and extended, and are widely used in the preparation of safety cases see Pitblado el al. (1990). 

Safety professionals from these vendors can provide additional guidance on which dust masks, respirators, safety suits, and gloves are most appropriate for varying needs. They can also specify the exact respirator cartridges needed to protect against a specific list of contaminants of concern. 

For this reason, NCRP recommends that emergency response personnel and first response vehicles should be equipped with radiation detection equipment to alert them for a radiologically compromised environment. Furthermore, this equipment should be designed to alert the responders when unacceptable ambient dose rates or dose limits are reached. Responders should wear appropriate personal protective equipment (e.g., chemical safety suits, respirators).

The UK government enquiry into the Piper Alpha disaster in the North Sea in 1988 has had a significant impact on working practices and equipment and has helped to improve offshore safety around the world. One result has been the development of a Safety Management System (SMS) which is a method of integrating work practices, and is a form of quality management system. Major oil companies have each developed their own specific SMS, to suit local environments and modes of operation, but the SMS typically addresses the following areas (recommended by the Cullen Enquiry into the Piper Alpha disaster) ... 

Early fluorescent pigments were promoted and adopted for use in screen inks for poster boards and paints for safety applications. These thermoset pigments were not well-suited because of their poor fightfastness. Also, because of their relatively coarse particle size, their use in thinner film applications, such as gravure or flexo, was limited. 

Laboratory work with hydrogen cyanide should be carried out only in a well-ventilated fume hood. Special safety equipment such as air masks, face masks, plastic aprons, and mbber gloves should be used. A chemical proof suit should be available for emergency. Where hydrogen cyanide is handled inside a building, suitable ventilation must be provided. The people involved should be thoroughly trained in first aid. 

Expertise—A client may seek to issue a toll contract if it chooses to produce a new product of unfamiliar chemistiy or formulation type. A toller may already have knowledge, equipment, and personnel uniquely suited for a given process that cannot be readily duplicated. A toller with expertise in that particular type of chemistiy or formulation could speed production and assist them in building a higher level of in-house expertise through close interaction. This may enhance the level of process safety and personnel safety should the client ever bring the process in-house. 

The weights for each component shown indicate that this particular accelerator is suited for mounting on a truck or trailer. The distances between each component are employed to ensure the safety of the workers involved in the repair (see Safety Requirements section). 

Make a list of chemical flocculating agents and relate each of these chemicals to the specific types of contaminants they are best suited to handle in wastewater. Obtain MSDS (Material Safety Data Sheets) for each of these chemicals. 

One of the key elements in laminated composite structures design is the ability to tailor a laminate to suit the job at hand. Tailoring consists of the following steps. We want to design the constituents of the laminate, and those constituents include the basic building blocks of the individual laminae and as well how they are oriented within the laminate. We design those constituents to just barely meet (with an appropriate factor of safety) the specific requirements for, say, strength and stiffness. 

While a multidisciplinary team approach is ideally suited to PSM design and installation, it is not the only way. PSM goals can be achieved through the efforts of a single professional, or a small homogeneous task group (for example, facility managers or safety specialists) the process is essentially the same as described here, but on a smaller, more limited scale. 

With proper equipment and suiting attempt to control and contain tlie hazindous material, fire, or other event. Consider the nature and quantity of tlie material tliat could be involved in your response to tlie situation.
