How Shanghai Bohua’s Enclosed Emergency Shower & Eyewash Protected Workers in a Sub-Arctic Chemical Facility
Client Profile
· Industry: Chemical Manufacturing & Processing
· Location: Northern China (Seasonal temperatures dropping to -30°C / -22°F)
· Facility: A large-scale petrochemical plant handling corrosive acids and alkalis.
· Challenge: Providing year-round compliant emergency safety equipment in an unheated outdoor loading bay.
The Challenge: The Danger of Frozen Safety Equipment
The client operated a hazardous chemical loading bay where workers were at risk of chemical splashes. Initially, the facility utilized standard outdoor emergency showers. However, during the harsh winter months, the water supply and residual water in the pipes would freeze, rendering the safety equipment completely inoperable.
1. Non-Compliance: Frozen equipment violated strict OSHA and Chinese national safety standards (GB/T 38144.1-2019), which mandate that tepid water must reach the affected area within seconds.
2. Delayed Treatment: In the event of a splash, workers had to run hundreds of meters to the nearest indoor safety station, losing precious seconds that could result in severe chemical burns or eye damage.
3. Hypothermia Risk: Using ambient outdoor water on a worker in freezing temperatures could induce shock or hypothermia, creating a secondary medical emergency.
The Solution: Shanghai Bohua Enclosed Emergency Shower & Eyewash
After a site inspection by Shanghai Bohua’s engineering team, the client installed the Bohua Model EN-3000 Enclosed Emergency Shower and Eyewash Station at the loading bay.
The Bohua EN-3000 is a self-contained, weatherproof unit designed specifically for harsh environments. Key features deployed included:
· Insulated Enclosure: A robust, double-walled, corrosion-resistant plastic shelter that protects the user from wind, snow, and ambient cold while they decontaminate.
· Anti-Freeze Protection: The unit was equipped with a thermostatically controlled heating system and insulated piping, ensuring that water temperature remained at a tepid 20°C–25°C (68°F–77°F) even when the external temperature dropped to -30°C.
· Instant Activation: Floor-level treadle plate activation allows hands-free operation, ensuring contaminated workers do not have to use their hands to start the shower.
· Self-Contained Draining: The unit features a contained drain system to prevent ice slicks from forming around the facility.
Implementation
Shanghai Bohua provided end-to-end support:
1. Site Assessment: Determined the optimal location to ensure the unit was within the required 10-second reach from the hazard zone.
2. Customization: Pre-set the thermostatic mixing valve to the specific ambient conditions of the site.
3. Installation & Commissioning: Connected the unit to the plant’s water and power supply and tested all heated components and flow rates to ensure compliance.
The Results
Since the installation of the Bohua BH32-1102, the chemical plant has reported zero downtime for their safety systems during winter months.
· 100% Operational Reliability: The enclosed and heated design eliminated equipment freezing, ensuring 24/7 compliance with safety regulations.
· Enhanced Worker Confidence: Employees reported feeling safer knowing that immediate and warm decontamination was available regardless of the weather.
· Rapid Emergency Response: In one recorded incident six months post-installation, a worker received a minor alkali splash to the forearm. They were able to enter the Bohua enclosure, remove contaminated clothing, and flush the affected area with tempered water within seconds, preventing any long-term injury.
· Reduced Liability: The facility manager noted that the installation of the enclosed unit significantly lowered the plant's risk profile and insurance liability regarding cold-weather operations.
Why Bohua?
This case study demonstrates the critical importance of matching safety equipment to the environment. While standard eyewashes work in a warehouse, extreme environments require the engineered protection of a Shanghai Bohua Enclosed Emergency Shower.
