See the answer below

Step-by-step explanation:

Although there are no specific options available to choose from, some of the general safety measures or precautions that must be observed when using a bunsen burner are as follows:

• Always leave, at least, 12 inches of space between the bunsen burner and the nearest object. This is to avoid the nearby object catching fire accidentally.
• Always watch the flame at all times, never leave it unattended to.
• Burners should not be handled unless ample time has been given for them to cool down. This is to avoid burning-related injuries.
• Burner fittings should be carefully checked to ensure there are no leakages. Gas leakages may cause serious accidents.
• Always use a sparker as this is safer than using matches or lighter.
• The gas supply must always be turned off whenever the burner is not in use.
