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:
- <em>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.</em>
- <em>Always watch the flame at all times, never leave it unattended to.</em>
- <em>Burners should not be handled unless ample time has been given for them to cool down. This is to avoid burning-related injuries.</em>
- <em>Burner fittings should be carefully checked to ensure there are no leakages. Gas leakages may cause serious accidents.</em>
- <em>Always use a sparker as this is safer than using matches or lighter.</em>
- <em>The gas supply must always be turned off whenever the burner is not in use.</em>
