## What Kind of Scuba Diving Tank Was Rob Stewart Using?
**Introduction**
Rob Stewart, a renowned Canadian filmmaker and conservationist, tragically died in a scuba diving accident in 2017. The circumstances surrounding his death raised questions about the type of diving tank he was using. This article explores the details of Stewart’s diving equipment and examines the safety considerations related to scuba diving tanks.
**Stewart’s Diving Tank**
Rob Stewart was using a 100 cubic foot (CF) aluminum diving tank. The tank had a maximum diving depth rating of 130 feet. Stewart’s diving profile indicated that he exceeded this depth limit, reaching a depth of approximately 150 feet.
**Types of Scuba Diving Tanks**
There are two main types of scuba diving tanks:
* **Steel Tanks:** Known for their durability and lower buoyancy, steel tanks are typically used by technical divers and in colder water conditions.
* **Aluminum Tanks:** Lighter and more buoyant than steel tanks, aluminum tanks are popular for recreational diving and in warmer waters.
**Depth and Tank Capacity**
The depth rating of a scuba diving tank is determined by its capacity and the pressure at which it is filled. A tank that is filled to a higher pressure will have a higher depth rating. The capacity of a tank is measured in cubic feet (CF), which represents the volume of air it can hold.
**Safety Considerations**
Using a scuba diving tank that exceeds its depth rating can be extremely dangerous. When a tank is used beyond its depth limit, the pressure inside the tank can cause the tank to fail, resulting in a catastrophic explosion.
**Additional Safety Measures**
In addition to using a tank with an appropriate depth rating, it is essential to take the following precautions:
* **Have your tank inspected regularly:** Scuba diving tanks should be inspected by a qualified professional on a regular basis to ensure they are safe for use.
* **Use a dive computer:** A dive computer provides real-time information about depth, time, and other dive parameters, helping divers stay within safe limits.
* **Follow the buddy system:** Diving with a partner is essential for safety and emergency assistance.
* **Be aware of your diving limits:** Divers should be aware of their own physical limitations and stay within their comfort zone.
**Conclusion**
Rob Stewart was using a 100 CF aluminum diving tank with a depth rating of 130 feet. It is believed that he exceeded this depth limit, which may have contributed to the tragic outcome. Understanding the importance of using an appropriate tank and adhering to safety precautions is critical for all divers. By following these guidelines, divers can minimize risks and enjoy the wonders of the underwater world safely.
