Safety requirements laboratories

Many operations involving chemical reactions are potentially dangerous, and in such cases recommended procedures must be carefully followed and obeyed. All laboratory workers should familiarise themselves with local safety requirements (in some laboratories, the wearing of safety spectacles may be compulsory), and with the position of first-aid equipment. 

H. Safety considerations. The Occupational Safety and Health Administration (OSHA), US Department of Labor, standard entitled Occupational Exposure to Hazardous Chemicals in Laboratories (29 CFR 1910.1450) makes it necessary to address safety issues in the SOP. The standard requires laboratories that use hazardous chemicals to maintain employee exposures at or below the permissible exposure limits specified for these chemicals in 29 CFR Part 1910, Subpart Z. Hazards associated with any specific chemicals used in a method must be addressed so that the user has the information needed to follow the Chemical Hygiene Plan for their laboratory. The method developer should limit the use of hazardous chemicals where feasible. The use of toxic and/or carcinogenic reagents should be avoided or eliminated as much as possible. Additionally, the cost of disposal is increasing and could impact the practicality of a method. Material Safety Data Sheets for the analyte(s) and any unusual or hazardous reagents should be provided for the user. 

Risk Categorization. The first step in this process is to clearly define the risk associated with the operation of this laboratory. This step includes a brief description of the operation followed by a risk assessment and a recommendation on the level of system safety required. 

Once the team is assembled, it is important to have a "kick-off" or pre-design meeting so that each representative is given the opportunity to present their needs and requirements. The remainder of this chapter will be devoted to health and safety requirements in the design of a research laboratory. 

At the outset of involvement in laboratory design it is incumbent for the health and safety specialists to designate those codes, regulations, and special requirements they consider essential to produce a safe and healthful work environment. All to often the A/E will choose a standard building code to follow. These codes, while appropriate for office buildings, do not address the necessary life safety requirements necessary for laboratories. 

Typically, the codes and regulations required for proper health and safety in laboratory design are the National Fire Protection... 

As this chapter has highlighted, sensorial experiment procedures allow students with visual impairments to actively participate in chemistry laboratories, along with nondisabled classmates. The instructional materials developed require minimal need of peripheral equipment, have comparable preparation times and cost to traditional laboratories, and are properly designed to fulfill safety requirements. The incorporation of available technologies into these experiments makes it possible to adapt these chemistry experiments to the needs of students with sensorial disabilities. As these experiments are disseminated and implemented in chemistry laboratories, the opportunity to encourage the interest of students with visual impairments to study chemistry increases. The prospect is to change mistaken views about the potential, inherent in all, to contribute and enjoy science. 

Microwave-assisted sample digestion has its own safety requirements. As a result of the direct energy absorption and rapid heating, microwave techniques introduce unique safety considerations that are not encountered in other methods. Differences in conditions between traditional laboratory practices and microwave-implemented methods should be examined before microwave energy is used to heat reagents or samples. An excellent suimnary of this aspects is given in the literature [18, 19, 175]. 

From Table 6.20, a standard filter has 250 fP (23.2 m ) of surface area. This choice will result in a safety factor of 29.5%. The final decision on the filter size, will require laboratory or pilot plant tests. In most cases, the filter manufacturer will provide this service. 

To be able to prepare annual reports, the sponsor s representative should know how the reports satisfy regulatory authority requirements. The clinical representative should be able to interpret clinical safety and laboratory findings. The ability to understand computer-generated clinical output and the organization and structure of the NDA/BLA/ MAA safety database is important. 

Special attention to safety requirements is necessary when performing site inspections. These include aspects in relation to the dosage form and activities observed (e.g. radioactive pharmaceuticals, hazardous materials, laboratory reagents, equipment and apparatus, explosions, personnel lifts, ladders, glassware, freezers, steam, radiation, microbiological hazards, viral and biological products and waste, and other relevant possible hazards).

To use high-energy radiation sources either in a laboratory or on an industrial scale, one must be familiar with their characteristics, the safety requirements and dosimetry. These topics are well covered in the literature and therefore will not be discussed [Bradley, 1984 Cleland, 1992 IAEA, 1994 Woods and Pikaev, 1994 Singh et al., 1996]. Usually, the suppliers of high-energy radiation equipment are also helpful in providing relevant information to their customers. 

Laboratory safety requirements. Escape of potent anti-ChE into the laboratory environment should be avoided by chamber design to prevent leaks into the atmosphere, including negative pressure differential with respect to the exterior. Protective clothing (including respiratory protective equipment), in the event of a leak or fur handling residually ctmtaminated animats, and appropriate first aid equipment and antidotes should be readily available. 

Check that the shift supervisors and laboratory personnel are aware of the test. They will tend to carry out their duties more carefully if they appreciate the importance of the test. Check for any last-minute safety requirements.

If this requirement is transferred to the determination of formal kinetic parameters, the boundary condition to be observed is that the safety technical laboratory experiment tries to imitate the actual plant conditions as exactly as possible. For example, this excludes the application of formal kinetic parameters obtained in a batch reactor for the prediction of the behaviour of a continuously stirred tank reactor. 

Commitment of management and involvement of workers (in this case, laboratory analysts), are essential. Management commitment to worker safety requires ...
