They were extracted from “Prudent Practices for Handling Hazardous Chemicals in Laboratories” (referred to below as “Prudent Practices”), which was published in 1981 by the National Research Council and is available from the National Academy Press, 2101 Constitution Ave., NW, Washington DC 20418. “Prudent Practices” is cited because of its wide distribution and acceptance and because of its preparation by members of the laboratory community through the sponsorship of the National Research Council.
However, none of the recommendations given here will modify any requirements of the laboratory standard. This appendix merely presents pertinent recommendations from “Prudent Practices,” organized into a form convenient for quick reference during operation of a laboratory facility and during development and application of a Chemical Hygiene Plan. Users of this appendix should consult “Prudent Practices” for a more extended presentation and justification for each recommendation.“Prudent Practices” deals with both safety and chemical hazards while the laboratory standard is concerned primarily with chemical hazards. Therefore, only those recommendations directed primarily toward control of toxic exposures are cited in this appendix, with the term “chemical hygiene” being substituted for the word “safety.” However, since conditions producing or threatening physical injury often pose toxic risks as well, page references concerning major categories of safety hazards in the laboratory are given in section F.
The recommendations from “Prudent Practices” have been paraphrased, combined, or otherwise reorganized, and headings have been added. However, their sense has not been changed.Corresponding Sections of the Standard and This AppendixThe following table is given for the convenience of those who are developing a Chemical Hygiene Plan which will satisfy the requirements of paragraph (e) of the standard. It indicates those sections of this appendix which are most pertinent to each of the sections of paragraph (e) and related paragraphs.Paragraph and topic in laboratory standard appendix sectionRelevant(e)(3)(i) Standard operating procedures for handling toxic chemicals.C, D, E(e)(3)(ii) Criteria to be used for implementation of measures to reduce exposures.D(e)(3)(iii) Fume hood performance.C4b(e)(3)(iv) Employee information and training (including emergency procedures).D10, D9(e)(3)(v) Requirements for prior approval of laboratory activities.E2b, E4b(e)(3)(vi) Medical consultation and medical examinations.
D5, E4f(e)(3)(vii) Chemical hygiene responsibilities.B(e)(3)(viii) Special precautions for work with particularly hazardous substances.E2, E3, E4In this appendix, those recommendations directed primarily at administrators and supervisors are given in sections A-D. Those recommendations of primary concern to employees who are actually handling laboratory chemicals are given in section E. (References to page numbers in “Prudent Practices” are given in parentheses.)A. General Principles for Work with Laboratory ChemicalsIn addition to the more detailed recommendations listed below in sections B-E, “Prudent Practices” expresses certain general principles, including the following:B. Chemical Hygiene ResponsibilitiesResponsibility for chemical hygiene rests at all levels (6, 11, 21) including the:C. The Laboratory FacilityD. Components of the Chemical Hygiene PlanE. Basic Rules and Procedures for Working with ChemicalsThe Chemical Hygiene Plan should require that laboratory workers know and follow its rules and procedures.
In addition to the procedures of the sub programs mentioned above, these should include the rules listed below.F. Safety RecommendationsThe above recommendations from “Prudent Practices” do not include those which are directed primarily toward prevention of physical injury rather than toxic exposure. However, failure of precautions against injury will often have the secondary effect of causing toxic exposures. Therefore, we list below page references for recommendations concerning some of the major categories of safety hazards which also have implications for chemical hygiene:G.

Bolsa Two Tone HoodieDesperate times require desperate measures – and when an impala was targeted by two vicious cheetahs, it made a jump for it that will not soon be forgotten.The distressed animal was captured on camera leaping into a car full of tourists in order to escape the predators.The terrified animal appeared to be seconds away from death when an unexpected window of opportunity appeared – quite literally. Close call: The impala jumps into a car to escape two cheetahs in Kruger National Park in South Africa The animal had been chased by the cheetah along with its herd when it realised it was the only one left behind. As the two ferocious animals appeared to have cornered the impala – it leaped into a nearby car which happened to have its windows rolled down. Samantha Pittendrigh, 20, happened to be filming the chase when the impala jumped through the passenger-side window of a Toyota in front of her. She said: ‘We started freaking out going crazy.
We couldn't believe it - we were absolutely dumbstruck. ‘We had absolutely no idea what was going on. ‘We watched the cheetah chasing theWe saw a few of them turn around in the bushes towards the road they were running from.' Sweet escape: A group of impala flee across a road in Kruger National Park, South Africa when one of them take an unexpected turn Swift exit: As the last impala cross the road, the cheetahs' intended meal finds a novel way to escape‘All of a sudden we saw the impala jump out of the bushes and then someone started screaming 'it is in the car, it is in the car'. ‘We heard a little girl screaming inThe boy sitting outside the car filming looked a lot younger, so it must have been a family. ‘People in other cars screamed 'open the door, open the door'.’ In the confusion, one of the passengers managed to open a door and the impala is seen just seconds later trotting across the road to freedom.
The cheetahs are just yards away but do not give chase. The footage was captured in Kruger National Park, South Africa, where according to park rules you must stay inside your vehicle at all times. As the terrified impala realises it is the cheetahs' chosen meal, it looks for a way out, and spots the car Unexpected visit: One person inside the car appears oblivious to the fact that an impala is on its way inside the vehicle and continues to film the cheetah chase Just dropping by: This is the moment when the impala jumps into the tourists' car in front of the chocked cheetahs The bewildered cheetahs are left with long noses and empty stomachs as the impala disappears into the carMiss Pittendrigh, who is studying supply chain management at the University of Pretoria, was with her friends Tanith Human, 20, Carmen Thvle, 21, and Michelle De Jager, 21. Unlike some of her friends, she has made several trips to Kruger National Park but was left stunned by the trip.
