Twisted twisters! Are your workplace tornado shelters ready?
Is your company ready when the skies go dark, and a tornado is on its way? Workplace tornado shelters can provide protection for employees during severe weather events, specifically tornadoes.
The specific requirements for workplace tornado shelters can vary depending on local building codes, regulations, and industry standards. Many companies assume OSHA requires tornado shelters, especially in states where tornadoes are common. However, there are no OSHA standards requiring shelters. OSHA does share best practice recommendations for protecting employees from severe weather on their Tornado Preparedness and Response page, such as:
- Design
- Location and signage
- Capacity
- Emergency supplies and communication
- Training
Design
Design and construct tornado shelters to withstand the high winds and flying debris associated with tornadoes. Build them with reinforced walls, roofs, and doors to provide a safe environment. Make the shelter accessible to all employees, including those with disabilities. Design it to accommodate individuals with mobility challenges and meet accessibility requirements.
Ensure the shelter has adequate ventilation to provide fresh air to occupants during their time in the shelter. This can be achieved through vents or mechanical ventilation systems that can operate even if power is lost.
Location and signage
In a tornado, employees need to get to the emergency shelter and get there fast. The shelters should be centrally located in the building, preferably on the ground floor or basement, where employees can get to them quickly. Install clear signage to guide employees to the tornado shelter, and educate employees about the shelter’s location, purpose, and how to safely utilize it during a tornado.
Capacity
Make sure the shelter has sufficient capacity to accommodate all employees and visitors in the workplace. The number of people the shelter can hold will depend on its size and the occupancy of the building.
Emergency supplies and communication
OSHA recommends a number of emergency supplies to be stored in the tornado shelter. It’s recommended to have emergency supplies stored in the tornado shelter, including first aid kits, flashlights, batteries, a battery-powered radio, and drinking water. These supplies can help occupants stay safe and comfortable until the all-clear is given. Check these supplies periodically to ensure they’re in place and ready to go at a moment’s notice.
A tornado’s destruction is likely to take down cellular communication towers, so shelter should have another means of communication, such as a two-way radio. This will allow occupants to contact emergency services or get updates on the situation outside, as well as communicate with other shelters in the building.
Training
Train employees on how and when to use the emergency shelter as part of an effective emergency action plan. Make sure the training covers topics such as understanding tornado watches and warnings and what actions to take during a tornado, such as where to go and when.
Additional requirements
While OSHA does not have a standard that requires tornado shelters, there may be local requirements that do. It’s essential to consult local building codes, regulations, and industry-specific guidelines when designing and constructing workplace tornado shelters. Local authorities, such as building departments or emergency management agencies, can provide specific requirements and recommendations based on the region and the nature of the workplace.
Key to remember
By putting these best practice recommendations into place, organizations can significantly enhance the preparedness of their employees and increase their chances of staying safe during tornado events. Remember, the safety of employees should always be a top priority and providing training and resources for tornado safety is a crucial part of that commitment.
