Prevention drowning

In this particular example, almost all recommendations can be implemented without difficulty. These technical improvements and new management systems will prevent future drown-... 

Zinc Amalgam. Hg—Zn. Amalgamated Zn residues, isolated from a Gemmenson reduction of an alkyl aryl ketone in glacial acetic acid, were found to be pyrophoric, and must be drowned in w immediately after flltm to prevent ignition Ref Bretherick (1979), 1012... 

Many loving parents probably instantly felt that alligators are a major concern. However, it could be that the real hazard was minimum supervision and shallow water. Countless young children unceremoniously drown, and little is said of that often preventable possibility. The National Safety Council stated that in 2000, 900 people drowned on home premises in swimming pools and in bathtubs. Of that number, 350 were children between newborn and 5 years old. [24] ABC News estimated that 50 young children drown in buckets each year, but we are familiar with buckets and do not see them as hazards. [25]... 

Drowned lime is produced when lime is slaked in excessive amounts of water so that the temperature required for effective slaking is not produced. A skin of lime putty seals the surface of the particles and prevents further slaking. 

Lifesaving appliances include a range of articles that prevent the loss of life, particularly through drowning, or increase the chances of survival. Many lifesaving appliances contain compressed gases ... 

A generic term for personal devices used to help prevent drowning should an individual inadvertently fall in the water or need assistance while swimming. 

Construction work over or near water is regulated under 29 CFR 1926.106. The purpose of the rule is to prevent drowning. The rule contains these requirements ... 

Cover the general requirements for fall protection in construction. If not only drowning hazards, but impact hazards, are involved, then fall protection, such as safety nets, safety harnesses, or guardrail systems, must be used to prevent employees from falling into the water. 

Superficially the simplest way to do this is to drown-out the reaction mass into water in order to recover product as a separate phase. This generates a ternary mixture of water/inorganic salt(s)/dipolar aprotic solvent from which it is not easy to recover quantitatively dry solvent. In the case of dimethylformamide a recovery option involving extraction with dichloromethane is available, but this is only viable for relatively concentrated aqueous solutions. Disposal to drain may be precluded in the case of nitrogen-containing solvents due to limits imposed on nitrogen levels in effluent to prevent eutrophication. Where possible the preferred recovery method is to filter off inorganics directly from the reaction mass and then recover dry solvent by distillation. 

Sadly, nearly all of these tragic deaths could be prevented. Most infant and child drownings occur when a child falls into a pool or is left unattended in the bathtub.

Of particular interest was the concept embodied in the remedy referred to as The Spirit of Human Blood as described by no less an authority than Robert Boyle. It was an uncommon remedy, for blood was not only a commodity that was not freely available, but healthy blood was in especially short supply, being drown from persons that parted with it out of custom or for prevention. To be safe and efficacious, it was essential that the blood was obtained from healthy individuals, since that acquired from persons of dubious health was clearly unlikely to be salubrious. The blood was dried, put in a retort, and heated on a sand bath, and the material distilled in this way was the spirit (spirit in this context was interpreted as the volatile salt of human blood). Boyle regarded it as an alkaline material similar to that obtained by distillation of hartshorn, urine, or sal ammoniac rather a disappointing substance compared to its name. 

Where any person is liable to fall into water or other liquid with a risk of drowning, suitable and sufficient steps must be taken to prevent, so far as is reasonably practicable, a person from falling and to minimise risk of drowning if people fall. Suitable rescue equipment must also be provided and maintained. 

The prevention of drowning is addressed by Regulation 14, which requires the taking of reasonably practicable steps to prevent falls into, and to minimise the risk of drowning in, water or any liquid where drowning could occur. Suitable rescue equipment is required. Transport by water to or from a place of work must be done safely, and any vessel used must be suitably built and maintained, not overcrowded or overloaded, and in the control of a competent person. 

The definition of confined space is very wide and includes any place such as trenches, vats, silos, pits, chambers, sewers, wells or other similar spaces which because of their nature could give rise to a specified risk . Specified risks are defined in Regulation 1. They include injury from fire or explosion loss of consciousness through a rise in body temperature or by asphyxiation drowning or from free-flowing solids causing asphyxiation or preventing escape from a space.
