## What is Commercial Scuba Diving?
Commercial scuba diving is a type of diving that is done for commercial purposes, such as construction, inspection, and maintenance. Commercial divers are trained to work in a variety of environments, including deep water, cold water, and hazardous materials. They use specialized equipment and techniques to perform their work safely and efficiently.
### Types of Commercial Scuba Diving
There are many different types of commercial scuba diving, including:
* **Construction:** Commercial divers may be employed to build and repair underwater structures, such as bridges, piers, and pipelines. They may also be involved in the construction of underwater habitats and research facilities.
* **Inspection:** Commercial divers may be hired to inspect underwater structures for damage or defects. They may also be used to survey underwater terrain and to collect samples of water or sediment.
* **Maintenance:** Commercial divers may be responsible for maintaining underwater structures, such as pipelines, cables, and buoys. They may also be involved in cleaning and repairing underwater equipment.
* **Hazardous materials:** Commercial divers may be called upon to work with hazardous materials, such as chemicals, explosives, and radioactive materials. They may be involved in the cleanup of spills and leaks, or in the disposal of hazardous waste.
### Training and Certification
Commercial divers must be trained and certified before they can work. The training requirements vary depending on the type of diving that is being done. However, all commercial divers must have a minimum of 200 hours of open water diving experience and must be able to pass a physical examination.
Once a diver has completed the required training, they must be certified by a recognized organization. There are a number of different organizations that offer commercial diver certification, including the American Academy of Underwater Sciences (AAUS), the Commercial Diving Academy (CDA), and the National Association of Underwater Instructors (NAUI).
### Equipment
Commercial divers use a variety of specialized equipment, including:
* **Diving suits:** Commercial divers use dry suits or wet suits to protect themselves from the cold water. Dry suits are airtight and keep the diver dry, while wet suits allow water to enter the suit but keep the diver insulated.
* **Helmets:** Commercial divers use helmets to protect their heads and faces from the water. Helmets also provide divers with a source of air and communication.
* **Boots and gloves:** Commercial divers wear boots and gloves to protect their feet and hands from the cold water and from sharp objects.
* **Tools:** Commercial divers use a variety of tools to perform their work, such as knives, hammers, and wrenches.
### Safety
Commercial scuba diving is a hazardous activity. Divers must be aware of the risks and take precautions to stay safe. Some of the risks of commercial scuba diving include:
* **Decompression sickness:** Decompression sickness is a condition that can occur when a diver ascends too quickly from deep water. Symptoms of decompression sickness can include pain, numbness, and paralysis.
* **Nitrogen narcosis:** Nitrogen narcosis is a condition that can occur when a diver breathes compressed air at depths greater than 100 feet. Symptoms of nitrogen narcosis can include confusion, euphoria, and hallucinations.
* **Oxygen toxicity:** Oxygen toxicity is a condition that can occur when a diver breathes pure oxygen at depths greater than 60 feet. Symptoms of oxygen toxicity can include seizures, convulsions, and death.
* **Drowning:** Drowning is the leading cause of death in commercial scuba diving. Divers must always be aware of the risks of drowning and take precautions to stay safe.
