When using a sodium hypochlorite spray gun for air disinfection, do operators need to wear protective equipment?

When using sodium hypochlorite spray guns for air disinfection, operators need to wear protective equipment to ensure safety and prevent disinfectants from causing irritation or injury to the human body. The following is a breakdown explanation:

1. Prevent inhalation of irritating gases
Reason: Sodium hypochlorite may release a small amount of chlorine gas or produce aerosol during the spraying process, which can have a stimulating effect on the respiratory tract.
Suggestion: Operators should wear protective masks (such as N95 or gas masks) to prevent inhalation of atomized particles or harmful gases.

2. Prevent eye irritation or injury
Reason: Nebulized disinfectant may float to the eyes, causing redness, swelling, stinging, or tearing.
Suggestion: Wear goggles or full face masks to protect the eyes from aerosol irritation.

3. Protect the skin from contact with corrosive liquids
Reason: Sodium hypochlorite has a certain degree of corrosiveness, and prolonged contact may cause skin dryness, cracking, or allergies.
Suggestion: Wear protective clothing, disposable isolation clothing or long sleeved work clothes, and wear chemical resistant gloves to avoid direct contact with spray.

4. Prevent accidental ingestion or contamination of clothing
Reason: It is possible to accidentally touch the mouth, nose, or clothing during the operation, causing unnecessary risks.
Suggestion: During the operation, avoid eating and speaking. After the operation is completed, change or clean clothes in a timely manner and clean exposed areas.

5. Preparation for emergency situations
Reason: If there is a leakage or unexpected high concentration during spraying, protective equipment can provide the first layer of safety barrier for operators.
Suggestion: Emergency eye wash equipment and clean water should be prepared on site for timely handling in case of accidental contact.

6. Comply with occupational safety regulations
Reason: According to hygiene disinfection and occupational health management regulations, equipment containing sodium hypochlorite disinfectants should be equipped with corresponding safety protection.
Suggestion: Follow the safety guidelines in the operation manual or industry standards to ensure personnel health and workplace safety.
