The Importance of Proper Water Temperature
Water that is hotter than 100°F (38°C) can result in scalding injuries, adding to existing injuries. High-temperature water can cause burns, leading to pain, skin damage, and an increased risk of chemical absorption into the skin. On the other hand, the improper use of cold water that is below 60°F (16°C) causes discomfort. In extreme cases, a cold shower can even lead to hypothermia, which can be life-threatening.
Tepid Water for Industrial Safety
The relevance of tepid water temperature in industrial safety often goes unnoticed but plays a vital role in the well-being of employees in various industries. It ensures that in the critical moments following an accident, first aid measures that use water do not unintentionally cause further harm, allowing for a more effective and safer response to workplace injuries.
It is important to understand the risks associated with improper water temperature especially when exposed to hazardous chemicals. Consider a chemical manufacturing plant where a worker accidentally splashes a corrosive chemical on themselves. Immediate access to a safety shower with tepid water is imperative. The proper water temperature helps to effectively rinse off the chemical without causing thermal shock or exacerbating the injury, which can be a serious concern with extreme water temperatures.
To prevent these dangers, the key is to ensure that the water temperature used in eyewash stations and emergency showers falls within the American National Standards Institute’s (ANSI) specified tepid range of 60 to 100°F (16 to 38°C). The emergency shower should have a minimum flow rate of 76 liters per minute of tepid water. Meaning, a continuous flow is required to allow a person to decontaminate for at least 15 minutes. This duration is essential to thoroughly wash away any hazardous chemicals from the skin and eyes, providing immediate relief and preventing the absorption of chemicals into the body.
Regulations on Tepid Water
Requirements and standards for tepid water in the industrial workplace in the United States are primarily outlined by the American National Standards Institute (ANSI) and enforced by the Occupational Safety and Health Administration (OSHA). These guidelines are crucial for ensuring worker safety, particularly in environments where hazardous materials are handled.
The most significant standard related to tepid water in the workplace is covered by ANSI/ISEA Z358.1-2014. It specifically mandates that emergency eyewash and shower equipment must provide tepid water. This requirement ensures that the water used in emergencies is not so cold as to cause hypothermia or so hot as to scald the skin or aggravate chemical reactions.
While OSHA does not specify temperature ranges for emergency eyewash and shower facilities, it does reference ANSI standards in its regulations. OSHA's General Duty Clause (Section 5(a)(1) of the Occupational Safety and Health Act) requires employers to provide a workplace free from recognized hazards. This includes providing appropriate emergency facilities, which, by industry best practices and ANSI standards, imply the availability of tepid water.
By setting these standards, ANSI and OSHA aim to reduce workplace injuries and ensure a safer working environment where risks associated with hazardous material exposure are properly mitigated.
Compliance
Compliance with regulatory requirements is not just a legal obligation but also a moral responsibility towards the safety and well-being of employees.
To ensure the safety and well-being of employees exposed to hazardous materials, facilities equipped with safety showers and eye/face wash stations must comply with the regulatory requirements and standards. Adhering to these regulations is essential for the proper installation, operation, and maintenance of safety shower systems.
Compliance with regulatory requirements involves conducting regular inspections and testing of safety showers to ensure they are in proper working condition and capable of delivering tepid water within the specified temperature range. It also includes maintaining appropriate signage, clear operating instructions, and adequate training for employees.
Additionally, facilities should have a documented emergency response plan that outlines the steps to be taken in the event of a chemical splash incident. This plan should include information on activating safety showers, the location of emergency eyewash stations, and the importance of using tepid water for decontamination.
Sanctions
There are sanctions for violations related to non-compliance with tepid water regulations in industrial settings, particularly under the guidelines set by the Occupational Safety and Health Administration (OSHA) in the United States.
If an employer fails to comply with ANSI/ISEA Z358.1-2014 standards, which include the provision of tepid water in emergency eyewash and shower stations, OSHA can impose penalties. These violations fall under OSHA's purview because they are considered a part of providing a safe and healthful workplace, as mandated by the Occupational Safety and Health Act.
The types of sanctions for such violations can include:
- Fines and Penalties: OSHA can levy significant fines on employers for non-compliance. The amount of these fines depends on the nature and severity of the violation. Serious violations, where there is a substantial probability of death or serious physical harm, can result in higher penalties.
- Citations: OSHA may issue citations to employers who fail to meet safety standards. These citations often require employers to correct the violation by a specific deadline and may also include a penalty.
- Increased Scrutiny and Follow-Up Inspections: An employer who violates OSHA standards may be subjected to increased scrutiny and follow-up inspections to ensure compliance.
- Legal and Civil Liabilities: Apart from OSHA sanctions, employers may face legal actions, including civil lawsuits from employees who are injured due to non-compliance with safety standards. This can lead to substantial legal costs and damages.
The goal of these sanctions is not just to penalize non-compliance, but more importantly, to ensure that workplace safety standards are upheld to protect employees from avoidable injuries and health hazards. Compliance with tepid water requirements in emergency eyewash and shower stations is a critical component of these safety measures.
