When a safety match ignites and burns is it a physical or chemical change?

I have this same worksheet that has the following questions that I have to answer: Iron rusts. Sodium hydroxide dissolves in water. A safety match ignites and burns. A cube of ice melts to form a puddle of water. Icicles form at the edge of a rof. Water is heated and changed into steam. Milk goes sour. A chocolate bar melts in the sun. Acid on limestone produces carbon dioxide gas. Vinegar and baking soda react. A tea kettle beings to whistle. Wood and leaves rot to form humus. So, I believe that a safety match igniting and burning is a chemical change. I have many Wiki results from that, and some put physical change. I don't think it's a physical change because the fire is on the match, and once it blows out, it creates that black substace which ISN'T fire. It creates a new substance that wasn't there before. Basically, the red part of the match and the fire created that new substance. I hope this helped! Sorry if this is wrong info. *-*

Is it a chemical change when a safety match ignites and burns?
Antimony trisulfide and sulfur provide the fuel for the match, which is ignited by a combination of red phosphorus (on the matchbook) and potassium perchlorate (coating the match). When friction heats the red phosphorus, some becomes white phosphorus and reacts with the perchlorate. This is sufficient to ignite the trisulfide and sulfur.

What safety precautions must be observed in chemical experiment?
wearing safety goggles.
What is a Material Safety Data Sheet?
A Material Safety Data Sheet (MSDS) is a document that contains information on the potential hazards (health, fire, reactivity and environmental) and how to work safely with the chemical product. It is an essential starting point for the development of a complete health and safety program. You can get this Material Safety Data Sheet from authorisations as like "International Chemical Safety Data Solution"
How do you change from a safety flame to a roaring flame?
to change from a safety flame to a roaring flame you would fully open the air hole.

Why do grenades explode when you pull the pin?
They DON'T explode when you pull the pin. There are three safeties on a grenade: the safety clip, the pin and the handle. The pin is the second safety you release. When all three safeties have been released, there's a little plunger under the handle that ignites a delaying charge. When the charge burns down to the end of the fuze, it ignites a primer that causes the grenade's filler to explode.
List down some of the laboratory precautions?
