Breathing masks

Systems worn by a person are not included here. These include personal fresh air supply systems (with pressurized air flasks or connected to a central system by tubes), air belts, air vests, and breathing masks. 

Substances, which after exposure can cause irritation leading to minor injuries only, even if no treatment is undertaken. They only require use of a breathing mask with cartridge. Also included are materials that give off irritant fumes in fire conditions and those that are an irritant to skin without causing any destruction of the tissues. 

The enthalpy of absorption of 1- and 2-nitropropane on breathing mask cartridges made with carbon is such that the decomposition of the nitrated derivative can cause its ignition. This accident is aggravated when the cartridge also contains metal oxides such as copper (II) oxide or manganese dioxide. 

For handling acrolein, gloves, vapor-proof goggles or a full face mask, and other protective clothing are mandatory (Albin 1962 Beauchamp et al. 1985 NIOSH 1990). Acrolein spills should be neutralized with 10% sodium bisulfite solutions (Albin 1962). Air packs or fresh-air breathing masks, safety showers, and eye baths should be available wherever acrolein is handled (Beauchamp...

Exposure to aluminum is usually not harmful. Aluminum occurs naturally in many foods. Factory workers who breathe large amounts of aluminum dusts can have lung problems, such as coughing or changes that show up in chest X-rays. The use of breathing masks and controls on the levels of dust in factories have eliminated this problem. Some workers who breathe aluminum dusts or aluminum fumes have decreased performance in some tests that measure functions of the nervous system. Some people who have kidney disease store a lot of aluminum in their bodies. The kidney disease causes less aluminum to be removed from the body in the urine. Sometimes these people developed bone or brain diseases that doctors think were caused by the excess aluminum. Some studies show that people exposed to high levels of aluminum may develop Alzheimer s disease, but other studies have not found this to be true. We do not...

Both Na and K are involved in various electrophysio-logical functions in higher animals. The [Na ] [K ] ratio is different in intra- and extra-cellular fluids, and the concentration gradients of these ions across cell membranes are the origin of the trans-membrane potential difference that, in nerve and muscle cells, is responsible for the transmission of nerve impulses. A balanced diet therefore includes both Na and salts. Potassium is also an essential plant nutrient, and salts are widely used as fertilizers. Uses of Li and Na in batteries are highlighted in Box 10.3, and the use of KO2 in breathing masks is described in Section 10.6. 

The alkali metal oxides, peroxides and superoxides react with water according to equations 10.11-10.13. One use of KO2 is in breathing masks where it absorbs H2O producing O2 for respiration and KOH, which absorbs exhaled CO2 (reaction 10.14). 

Use a well-fitting face (breathing) mask rated for toxic dusts . Masks rated for nuisance dusts are better than nothing but do not offer sufficient protection. If there is significant dust in the air, the mask should cover the eyes, as well.

Ventilators are either negative-pressure or positive-pressure. Negative-pressure ventilation involves directing air directly into the lungs, and positive-pressure ventilation involves directing air into the trachea. Some ventilators require intubation, the placement of a tube into the trachea from the nose or mouth. Ventilation requiring intubation is typically used for patients who will require ventilation for a protracted period. Other ventilators work with a breathing mask that can be placed over the mouth and nose. With the increase in respiratory-related sleep disorders (such as obstructive sleep apnea), use of two positive airway pressure systems—continuous positive airway pressure (CPAP) and bilevel positive pressure ventilators (BiPAP)—has become very common. 

Each of these hazards would be eliminated by the provision of suitable and adequate exhaust ventilation or, in the case of silicosis, by the provision of suitable breathing masks. In each case food should not be consumed in the area, and the medical conditions can be exacerbated through habitual smoking. A good standard of personal hygiene is also an important factor in maintaining good health on site.
