For hazardous substances not classified as carcinogens, where protection of exposure is not reasonably practicable, adequate control should be achieved by measures odier than personal protection, so far as is reasonably practicable. Tliis is subject to the degree of exposure, circumstances of use of the substance, informed knowledge about the hazards and current technical developments. Any combination of the measures listed in Table 5.22 are applicable. 

Platinum is used as a catalyst for nitric and sulphuric acid production, in petroleum refining and in catalytic mufflers to control air pollution. Platinum salts can cause respiratory complaints, asthma, and platinosis , an allergic response. Allergic dermatitis may also result from exposure to soluble platinum salts and once subjects have been sensitized it generally precludes continued occupational exposure at any level. The 8 hr TWA OEL for platinum metal is 5 mg/m but for soluble platinum salts it is only 0.002 mg/m. Handling precautions must include containment where possible, ventilation, personal protection, and the screening out of individuals who have become sensitized. 

Protection Factor The ratio of the concentration outside the personal protective equipment to the concentration inside the personal protective equipment. Measurement site are critical for proper determination (e.g., for a protective mask, the measurement inside the mask would be made at a subject s breathing zone, and the measurements outside the mask would be made in a corresponding zone). 

Inventions are property and are generally owned by the person who created them they receive protection under the law in the same way that other property receives protection. However, the property in an invention that is the subject of protection under the law is not the idea behind the invention but the tangible reduction to practice... 

To assess the exposure of sprayers employed in motor vehicle repair shops, Williams et al. also explored biomonitoring methods to measure urinary HDA by GC-MS. Samples were collected among sprayers wearing personal protective equipment and spraying in booths or with local exhaust ventilation, from bystanders, and from unexposed subjects. HDA was detected in four sprayers and one bystander out of 22 workers, while it was not detected in samples from unexposed persons. They concluded that exposure to isocyanates still occurred despite the use of personal protective equipment and the use of a booth or extracted space, and that health surveillance is likely to be required to provide feedback on the adequacy of controls, even if such precautions are used, and to identify cases of early asthma. 

The control of chemical hazards at SNL is documented in the Primary Hazard Screen and Hazard Analysis process for every project or facility. Work-specific technical work documents provide more detailed chemical hazard controls. Hazard control is based on the hierarchy of controls engineering controls first, administrative controls next, and personal protective controls last. ES H subject matter experts provide input on appropriate controls to chemical users and their management. 

Interestingly, applicators on open vehicles wore protective devices and thus were still protected when events caused them to dismount. However, the apparent security afforded by spray cabs caused several subjects to work without coveralls, shirts, gloves, hats and respirators, and they were very vulnerable when they had to leave their protected environment to deal with minor problems. Spray cabs usage was. In fact, Increasing the risk of potential exposure under certain circumstances by abetting their neglect of personal protection. 

One of the two nanoparticles that was the subject of the November 2008 SNUR is a siloxane modified silica nanoparticle, and the other is a siloxane modified alumina nanoparticle. EPA explained in the SNUR that it was concerned about dermal and inhalation exposures for new uses that were not described in the PMNs filed for those substances. It suggested that a ninety-day inhalation toxicity test would help characterize the human health effects for each substance. The SNURs for these two substances say that it would be a significant new use to use either substance without specified personal protective equipment, for any use other than the uses specified in the PMNs for those substances, and to manufacture, process or use them in powder form. The preamble to the SNUR says that the PMNs do not claim confidentiality for use of these substances as additives, but the PMN for one of these substance clearly limits the kind of additive for which it was intended, but everything except the word additive is claimed as confidential. Therefore, any other entity that intends to manufacture, import, or process any nanoparticles described by the generic names for these substances should submit a bona fide letter to determine their exact chemical compositions and the specifics of what uses are significant new uses. 

Reducing the effects of vibration, shock, and impact on humans is effected in several ways (1) by isolation, to reduce the transmission of dynamic forces and accelerations to the body (2) by personal protective equipment, to distribute the dynamic forces over as large a surface area as possible and (3) by redesign, to reduce the source s vibration intensity. These subjects are considered after summarizing the occurrence of health effects from exposure to vibration, shock, and impact, which establishes the performance required of ameliorative measures. 

The Coast Guards of Canada and the United States, each with its own added requirements, regulate barge transport of chlorine (P79). There is not yet a Coast Guard-defined procedure for emergency response plans, but training is covered in 29 CFR 1910.120. This also covers procedures, clean-up activities, and the use of personal protective equipment. Protective equipment is also the subject of Cl Pamphlet 65 and 29 CFR 1910.132-134. 

This is a confined space that is a part of, and contiguous with, a larger confined space (for example, sewers) that the employer cannot isolate from the larger confined space. It is also subject to a potential hazard release from the larger confined space that would overwhelm personal protective equipment and/or hazard controls. This would result in a hazard that is immediately dangerous to life and health. 

A previous, completely recovered ICD should not be considered as a hypersusceptible condition. For these subjects, in case of exposure to irritant or allergenic sustances, the common preventive measures (environmental prevention, information, effective personal protective devices) are sufficient...
