After-Hours Working

After-hours work Unusual operations outside of normal working hours unattended operation. Responsibility on- and off-site should be established, and emergency contact names and telephone numbers should be available to security personnel. [Pg.320]

Develop a written Fire Prevention Plan for regular and after-hours work conditions. [Pg.318]

Coal mining has been a relatively dangerous occupation (2,91—93). During the period from 1961—1967 the average fataUty rate in the United States for each million person hours worked was 1.05. In the seven years after the passage of the Eederal Coal Mine Health and Safety Act of 1969, the average fatahty rate decreased to 0.58, and by 1989 the rate was 0.25 (2). [Pg.233]

I developed the concept for Power Supply Cookbook after having spent many hours working with design engineers on their power supply designs and, subsequently, my own designs. [Pg.268]

Air samples are collected over an 8 hour work shift for MEK. Measurements showed 3 ppm after 2 hours, 24 ppm after 4.5 hours, 12 ppm after 6 hours, and 2 ppm after 8 hours. Caleulate the TWA concentration and compare this value against the OSHA safe level of exposure. [Pg.279]

This increase in productivity is accounted for partly by a decrease in absenteeism and accidents as well as a general increase in working efficiency. For example, Vernon (1918), found that when women in a munitions factory worked a 12-hour day they incurred 2.5 times more accidents than when they worked a 10-hour day. One of the more comprehensive studies of the effects of total hours of work was carried out after World War II by the U.S. Department of Labor (Kossoris and Kohler, 1947). This covered over 3500 men and women in 78 work units. Data were collected on accidents and absenteeism as well as productivity. The overall findings were that exceeding the 8-hour work day, 5 days/40 hours work week resulted in lower productivity and higher absenteeism and accident rates. [Pg.113]

Threshold Limit Value - Time Weighted Average (TLV-TWA), this is the time-weighted concentration for a normal 8-hour work day or 40 hour working week, to which nearly all workers may be repeatedly exposed, day after day, without adverse effects. [Pg.66]

Ed is a 38-year-old EAP caseworker and this Wednesday afternoon is visited by George, who tells Ed that his wife is tired of his smoking marijuana. George makes it clear that he does not smoke at work or on the premises, but admitted that he may smoke too much from time to time on the weekends and with friends after hours during the week. George tells Ed he just wants to get his wife off his back and does not know what the big deal is after all, he works hard for the family and she should appreciate his efforts rather than complaining about how he relaxes. However, he promised his wife that he would stop by and see an EAP representative. [Pg.104]

Oppolzer and Battig have prepared the marine sesquiterpene via ingenious application of iterative intramolecular magnesium-ene reactions . Aldehyde 672 was converted to the allylic chloride 673, the Grignard of which was heated at 60 °C for 23 hours and subsequently treated with acrolein to furnish alcohol 674 (Scheme LXX). An analogous sequence transformed 675 to 676 and set the stage for final transformations which were patterned after earlier work. [Pg.63]

The project also highlighted that my preference previously was to pursue comfortable rather than effective behaviours. For example, it was easier to work on projects after hours as 1 would not then be interrupted, and to do my own filing as this would be easier to do myself. Thus my need for comfort may have been causing me to do things that were counterproductive. [Pg.67]

A sharp decrease in the hydroxyl concentration was observed when small amounts of CO or of hydrocarbon penetrated into the discharge tube. It might be such as to prevent detection of hydroxyl by its absorption spectrum. In order to restore the hydroxyl concentration it was necessary to clean the discharge tube and the reaction vessel by means of a discharge with water vapor lasting for several hours. For instance, after having worked with benzene without controlling the presence of hydroxyl, the latter was not detected in the reaction vessel. [Pg.33]

Standard Heck coupling of o-bromopropiophenone with propyne proceeds in 72% yield. Deprotonation of the product thus formed with KHMDS in toluene at -78°C followed by heating at 75°C for one hour gave 3-methyl-1-naphthol in 74% yield after acidic work-up and distillation. This approach has proved to be general and efficient for the preparation of a variety of 3-alkyl-1 -naphthols. [Pg.28]

Butyl benzoate. Use 30 g (0.246 mol) of benzoic acid, 37 g (46 ml, 0.5 mol) of butan-l-ol, 50 ml of sodium-dried toluene and 10g (5.4 ml) of concentrated sulphuric acid, and reflux the mixture for 12 hours. Work up the product as for propyl benzoate after the ether and toluene have been removed with the aid of a rotary evaporator, distil the residue under reduced pressure. The yield of butyl benzoate, b.p. 119-120 °C/11 mmHg, is 35 g (80%). [Pg.1078]

HUMULIN-R day 1-7 was injected first thing upon waking then again 4-6 hours later, immediately after a work-out. lOOg of high glycemic carbs was consumed each hour for 4-6 consecutive hours following injections. Each HUMULIN-R injection was 13 i.u. The two injections were not allowed to over lap (6-8 hours apart). [Pg.126]

Threshold limit value (TLV) The maximum concentration of a chemical substance in air that a worker can be exposed to day after work day without suffering any harmful effects. Typically, TLVs are guidelines or recommendations rather than enforceable standards. Like permissible exposure limits (PELs), TLVs are often given as time weighted averages (TWAs) for an 8-hour work day (compare with action level and permissible exposure limit). [Pg.469]

The oxidation is performed in dichloromethane or chloroform at room temperature, and is usually complete within 0.5 - 2 hours. Products are easily separated from the iodo-compound byproduct after basic work-up. [Pg.94]

They didn t know about Shifty at the hospital, her thoughts on the universe sex and religion or what she got up to after hours, just like they didn t know what the head of Gastroenterology did in city toilets. They didn t know about the Professor at university, his acid parties and husky school trade. At the office, interstate, they didn t know about James, his repertoire of outfits like a book of bad fairy tales cataloguing almost twenty years on the dancefloor and his true passion music. Slip s buried as well beneath kitchen chores four nights a week. They knew a little of Turkish Jim, Bee and Holmes in their more lateral work environments, just as they had glimpsed Billy s other lives... [Pg.302]
