no they do not. they contain carbon dioxide, potassium bromide, and chalk. nothing in that is harmful.
respiratory problems, asthma and allergies can be caused by inhaling powder lighteners.
There are six classes of fires to define the type of fire, and most importantly, the type of fire extinguisher to use to put out the fire. Here are the fire classes and the types of extinguishers you should use: Class A - Solids (wood, paper, plastic) require water, foam, dry powder, and wet chemical extinguishers. Class B - Flammable liquids (fuel, oil, paraffin) require foam, dry powder, and CO2 gas extinguishers. Class C - Flammable gasses (propane, methane, butane) require dry powder extinguishers. Class D - Burning metals (aluminum, magnesium, titanium) require dry powder (M28/L2) extinguishers. Class E - Electrical items require dry powder or CO2 gas extinguishers. Class F - Cooking oils and fats require wet chemical extinguishers.
I don't know if my answer is right, but if baby powder causes cancer, they would of taken it off the shelves ages ago. From my personal point of view, baby powder does not cause cancer. There is little or no research saying baby powder causes cancer. If it does, then the chances would be near astronomical because baby powder is very commonly used, with, as far as I know, no cases of cancer. (It is more likely that cases of cancer in patients who have used baby powder is pure coincidence.)

Only if the inhalation was for long periods or if the inhaled quantity of zirconium fine powder was great.
The white stuff in fire extinguishers is typically a chemical called dry chemical powder or monoammonium phosphate. This powder is a fire suppression agent that is effective for extinguishing different types of fires, such as those involving flammable liquids, gases, and electrical equipment. When released, the powder smothers the fire and helps to cool the fuel, preventing it from reigniting.
There really aren't impacts on the environment, unless you were to spray the Dry powder outdoors for no reason.
Type 'B' which can be used on petrol, diesel or oils. That is either a Foam or a Powder extinguisher. Foam extinguishers usually contain additives that are carcinogenic. Care should be taken with the cleaning up process after the fire has been put out. Care should be taken whilst using powder units in confined spaces, do not inhale the powder
Fire extinguishers should be inspected annually - by a suitably qualified person.
Most extinguishers have a pressure gauge which has a Red Zone marked for full pressure. Just look to see if the needle indicated pressure at near the Full mark. Also, most extinguishers are filled with powder. This powder can pack down and cake when not agitated. It is a good idea to turn the extinguisher over, upside down several times. You will feel the powder move about inside the housing.
A 'dry powder' extinguisher. Water or foam extinguishers will destroy the circuits (and shouldn't be used on electrical fires).
