What happens if br is spilled on your skin
Minus Related Pages. What bromine is Bromine is a naturally occurring element that is a liquid at room temperature. It has a brownish-red color with a bleach-like odor, and it dissolves in water. Bromine can also be found as an alternative to chlorine in swimming pools. Products containing bromine are used in agriculture and sanitation and as fire retardants chemicals that help prevent things from catching fire. Some bromine-containing compounds were historically used as sedatives drugs that can make people calm or sleepy.
However, these drugs are for the most part no longer found on the market in the United States. How you could be exposed to bromine Following the release of bromine into water, you could be exposed by drinking the contaminated water.
If food becomes contaminated with bromine, you could be exposed by eating the contaminated food. Following release of bromine gas into the air, you could be exposed by breathing the fumes. Skin exposure to bromine could occur through direct contact with bromine liquid or gas.
Bromine gas is heavier than air, so it would settle in low-lying areas. How bromine works Bromine works by directly irritating the skin, mucous membranes, and tissues. The seriousness of poisoning caused by bromine depends on the amount, route, and length of time of exposure, as well as the age and preexisting medical condition of the person exposed. Immediate signs and symptoms of exposure to bromine Breathing bromine gas could cause you to cough, have trouble breathing, get a headache, have irritation of your mucous membranes inside your mouth, nose, etc.
Getting bromine liquid or gas on your skin could cause skin irritation and burns. Brominated flame retardants crop up in a surprising number of places. From a bag, Anat produces, Mary Poppins-style, a series of products - white beads that are mixed into the plastic casings and circuit-boards of TVs and computers, fluffy yellow pillow stuffing that refuses to catch fire, and blue polystyrene bricks that are used as cavity wall insulation in homes.
Well, take for example, polybrominated diphenyl ethers PBDEs , which used to be widely used to prevent materials from melting. No longer. It is set to be banned in the EU next year, after an academic study in Texas in found that tiny amounts of the stuff were getting into some supermarket foods. The retardants are organic molecules - an entirely different class of chemical from bromide salts - that can take years to decompose. And although they should be tied up inside plastics and other materials, when they do get free they tend to accumulate through the food chain - meaning top predators such as humans face a particular risk of these chemicals slowly building up in our bodies.
This highlights an unavoidable problem for the chemicals industry - much of what they do is still a learning process, and it often takes many years for the long-term risks inherent in a particular product to emerge. Yet it is also important to get these risks in perspective. So far, there are no known cases of brominated fire retardants actually causing anyone major health problems - they are being banned because of the potential hazard they pose.
Meanwhile, these chemicals have undoubtedly saved people from the very real risk of burning to death in their own homes, although there is some dispute whether that amounts to the thousands per year claimed by the industry. But Laura Syrett says the industry also labours under another problem - "chemophobia". As an example she cites brominated vegetable oil or BVO , which was commonly added as an emulsifier in soft drinks such as Fanta and Gatorade. Without BVO or a substitute, the orange colour would gravitate to the bottom of your bottle, leaving the top half clear.
Something similar would happen to the flavour. The list included BVO - banned in the EU and Japan - which it claimed was "linked to major organ system damage, birth defects, growth problems, schizophrenia, and hearing loss".
Nonetheless, a petition on Change. Was the campaign against BVO rational? The chemistry blogger Derek Lowe points out that the few people known to have suffered health problems none of which were quite like those listed by Buzzfeed were drinking a vast amount of BVO-containing drinks - in the order of two to four litres per day. Another controversial case, according to Laura Syrett, is connected with fracking. In , tests of drinking water wells in Pennsylvania found increased levels of bromide salts - the same kind of stuff that supposedly makes people prefer an early night with a hot water bottle - linked to fracking activity at the Marcellus shale deposit.

Mackison, F. Stricoff, and L. Partridge, Jr. Immediately flush with lukewarm, gently flowing water for minutes. If irritation or pain persists, see a doctor. Double bag, seal, label and leave contaminated clothing, shoes and leather goods at the scene for safe disposal. Eye Contact: Avoid direct contact. Wear chemical protective gloves if necessary. Immediately flush the contaminated eye s with lukewarm, gently flowing water for minutes, while holding the eyelid s open. Take care not to rinse contaminated water into the unaffected eye or onto the face.
Ingestion: Have victim rinse mouth with water. If vomiting occurs naturally, have victim lean forward to reduce risk of aspiration. Have victim rinse mouth with water again. Immediately call a Poison Centre or doctor. First Aid Comments: If exposed or concerned, see a doctor for medical advice. All first aid procedures should be periodically reviewed by a doctor familiar with the chemical and its conditions of use in the workplace.
Note to Physicians: Some jurisdictions specifically regulate benzene and require a complete medical surveillance program. Specific information should be sought from the appropriate government agency in your jurisdiction. Can ignite at room temperature.
Releases vapour that can form explosive mixture with air. Can be ignited by static discharge. Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, appropriate foam, water spray or fog. Foam manufacturers should be consulted for recommendations regarding types of foams and application rates. Liquid can accumulate static charge by flow, splashing or agitation.
Vapour may travel a considerable distance to a source of ignition and flash back to a leak or open container. Vapour may accumulate in hazardous amounts in low-lying areas especially inside confined spaces, resulting in a toxicity hazard.
Closed containers may rupture violently when heated releasing contents. In a fire, the following hazardous materials may be generated: very toxic carbon monoxide, carbon dioxide; toxic, flammable aldehydes; and other chemicals.
Personal Precautions: Evacuate the area immediately Keep unnecessary and unprotected personnel out of spill area. Methods for Containment and Clean-up: Stop or reduce leak if safe to do so. Small spills or leaks: contain and soak up spill with absorbent that does not react with spilled product. Place used absorbent into suitable, covered, labelled containers for disposal.
