　　1.Production process
Whether toxic and harmful gases or chemicals are used in the production process can cause significant harm to the human body.An excellent engineer will consider these issues when planning and designing a cleanroom,and set up a sufficiently powerful exhaust system to promptly exhaust the generated gases indoors.As long as the exhaust system is installed properly,the fan power is sufficient,and harmful substances can be discharged in a timely manner,the harm to the human body will be greatly reduced or even eliminated.
2.Protective measures
When working near high radiation equipment,appropriate protective measures must be taken to avoid personal injury.
3.Strictly control the number of people
A dust-free workshop is a closed space that relies on air conditioning units to supply air according to the designed air volume.The number of people that can be accommodated in the dust-free workshop is limited.If there are too many hands,it may cause insufficient oxygen,making people feel dizzy and nauseous.
4.Fire evacuation
A reasonable and scientific dust-free workshop should be equipped with a fire protection system as required and ensure smooth evacuation routes.When an emergency occurs,take immediate response measures and evacuate personnel urgently.
