Bomb squad

Low molecular weight ether hydroperoxides are similarly dangerous and therefore ethers should be tested for peroxides and any peroxidic products removed from them before ethers are distilled or evaporated to dryness. Many ethers autoxidize so readily that peroxidic compounds form at dangerous levels when stored in containers that are not airtight (133). Used ether containers should be handled cautiously and if they are found to contain hazardous soHd ether peroxides, bomb-squad assisted disposal may be required (134). ZeoHtes have been used for removal of peroxide impurities from ethers (135). 

Every student who works in a chemical laboratory is warned that organic chemicals should never be stored for long times because they can explode without warning or apparent provocation. Bottles of organic chemicals should always be disposed of within a few years, and, if a chemical is found that might be very old, a bomb squad of safety experts should be called to remove it and properly dispose of it. 

Containers of di-isopropyl ether that have been opened, or have been stored for more than 3 months, may contain hazardous quantities of peroxides. Especially if crystals are present, the container should be handled only by appropriate authorities such as a bomb squad. Where the container can be opened safely, check for peroxides as follows Wear butyl rubber gloves, laboratory coat, and eye protection. Work in the fume hood. Dissolve 100 mg of potassium iodide in 1 mL of glacial acetic acid. Add to 1 mL of diisopropyl ether. A pale yellow color indicates a low concentration (0.001-0.005%) and a bright yellow or brown color indicates a high concentration (above 0.01% and hazardous) of peroxide in the sample.11... 

CAUTION Red phosphorus is a dangerous compound. Respirators should be worn while handling this component and care taken to ensure that the dust is not ingested, breathed or allowed contact with the skin. DO NOT use any container or other utensil that has at any time been used with potassium chlorate or any chlorate salt. An explosion is a certainty. I have a picture of a bomb squad crewmember with his hand turned into a mist by this compositions detonation and it does not look at all pleasant.

The letter was printed about 1972 and I sold a lot of PMJBs. Redstone Arsenal was conducting a training program for police bomb squads and so bought a couple of thousand copies,... 

If you are a bomb squad person your Hrsc act should be to assure minimum damage in case the bomb goes off before you can dispose of it. Having done this you must next remove the bomb from the area. 

I saw many such pictures during the recent rash of letter bombings. Bomb squad people would be wearing useless vests and carrying the vile letter bombs in their bare hands. Ignorant ... 

Peroxide crystals may form within the threads of the cap. and the act of removing the cap may cause a fatal detonation. A bomb squad may be required. 

Trinitrophenol, also known as picric acid, is composed of yellow crystals and is a nitro hydrocarbon derivative. It is shipped with not less than 10% water as a wetted explosive. There is a severe explosion risk when shocked or heated to 572°F, and it reacts with metals or metallic salts. In addition to being flammable and explosive, it is toxic by skin absorption. Picric acid has caused disposal problems in school and other chemistry laboratories where the moisture has evaporated from the container as the material ages. When the picric acid dries out, it becomes a high explosive closely related to TNT. Picric acid has been found in various amounts in school labs across the country. In a dry condition, picric acid is dangerous and should be handled by the bomb squad. The structure and molecular formula for picric acid are shown in Figure 6.3. 

Once a chemical or waste stream has become unsafe due to dehydration, solvent evaporation, or the formation of hazardous products, processes used to manage the material must be clearly defined in the chemical management program. Employees need to know if they call the professional expert designated by management, if they are to call the bomb squad or emergency response, etc. 

Meanwhile, police officers find, on the upwind side of the stadium in the parking lot, three 5-gallon LPG (liquid propane gas) tanks with hluish corrosion on their brass valves. The containers are X-rayed by the bomb squad. It is determined that they are empty and contain no explosives. Tests by hazardous materials technicians note no toxic materials other than low levels of ammonia. 

Before leaving your vehicle, call dispatch to notify all other responders, the fire service, EMS, medical control, receiving hospitals, law enforcement, the bomb squad, and hazardous materials assistance. 

The commitment of responders to scenes involving explosions should be based on a risk-benefit ratio. If there is no fire and no persons to be rescued, then do not enter the scene before the bomb squad clears the scene of secondary devices and partially consumed explosives. Know how to contact your local bomb squad and what their response time will be. 

Explosion scenes are not secure until bomb squad members have thoroughly assessed them for additional bombs, unconsumed explosives, chemical devices, biological agents, and radioactive materials. Remember, secondary devices may be present or there may be assailants waiting in ambush. 

The Bureau of Alcohol, Tobacco, Firearms, and Explosives sends its National Response Team to investigate and along with the local bomb squad concludes that the cause of the blast was in a bomb. This is confirmed by metal fragments... 

A student working in a laboratory needed a chemical for an experiment. While looking for this chemical he came across a bottle of isopropyl ether. He remembered that isopropyl ether was well known for explosions from peroxide formations. As he looked at it, it appeared to be filled with large crystals and he knew that it should be a liquid, not a solid. He reported this to his professor who came to look at the bottle too. The professor ordered everyone out of the stockroom and called local emergency response officials who sent out the bomb squad. The bomb squad removed the bottle for controlled detonation in an open field. 

It is not uncommon for an old bottle of picric acid to be discovered in a dry state—this is a dangerous occurrence and requires attention from emergency personnel and probably the local bomb squad. There are many incidents involving dried out picric acid within university settings. One report described the removal of several bottles of picric acid using a bomb squad robot and as the last bottle of picric acid was placed in the bomb container, it exploded, producing a crater. ... 

Puncture-Resistant and Cut-Resistant Clothing Police, secmity personnel, bomb squads and others need protection from ballistic objects. Body armor clothing provides this protection.
