When diving into the underwater world, you face not only the magic of the ocean but also formidable dangers. This article will guide you in exploring the underwater world and help you ensure health and safety in challenging jobs like scuba diving.
I. Introduction to working in an aquatic environment and its appeal
When we talk about working in an underground environment, we often think of complex and challenging jobs underground or underwater. This is a world completely different, where people must face conditions that require special preparation and expertise.
The aquatic environment is an important part of work in the oil and gas, mining, hydropower, and many other industries. Working in an aquatic environment requires technical knowledge, complex equipment, and the ability to work under high pressure. These jobs often attract people who want to challenge themselves and love exploration.
The underwater environment is a place of diverse flora, fauna, and interesting landscapes. Exploring and researching the underwater world brings valuable scientific discoveries about aquatic life, and it also contributes to protecting the environment and the planet’s water resources. You can see more details about occupational safety training duration under Decree 44.

II. Understanding the potential health risks when working underwater
Working underwater can be an exciting and challenging experience, but it also comes with potential health risks. Working in an aquatic environment requires technical preparation and the necessary safety knowledge to face the following risks:
- Lack of oxygen: When working underwater, the risk of oxygen deficiency is always present. Lack of oxygen can lead to hypoxia, endangering the health of the worker.
- Water pressure: Changes in water pressure can affect the body, causing undesirable effects such as decompression sickness, cardiovascular damage, and respiratory problems.
- Risk of toxic substance poisoning: In the aquatic environment, there is a risk of exposure to harmful substances such as pesticides, industrial chemicals, or pathogenic bacteria in the water.
- Weather and harsh environment: Factors such as low temperatures, bad weather, and changes in the aquatic environment can affect the health and safety of workers.
- Accidents and injuries: The underwater environment can create conditions for accidents such as collisions with obstacles, the risk of getting trapped, or injuries due to equipment failure.

III. Important methods to ensure safety when working in an aquatic environment
In the underwater work environment, ensuring safety is always a top priority. Here are some important methods to help ensure safety for people working in the aquatic environment:
- Training and Education: Ensure all underwater workers are fully trained and educated on safety. They need to master knowledge of how to handle emergency situations, use protective equipment, and safety rules in the aquatic environment.
- Equipment Inspection: Personal protective equipment and work equipment must be thoroughly inspected before use and regularly during work. This ensures they function correctly and are sufficiently safe.
- Adherence to Safety Rules: All underwater workers must comply with all regulations and safety rules related to the aquatic environment. Non-compliance can lead to dangerous accidents.
- Use of Safety Equipment: Use protective equipment fully and correctly, such as life jackets, masks, or troubleshooting tools. This helps protect workers from risks.
- Risk Control: Assess and control potential risks such as oxygen deficiency, pressure changes, or exposure to toxic substances. Countermeasures must be implemented to minimize these risks.
- First Aid Training: All underwater workers should be trained in rescue and first aid for colleagues in case of an emergency.

IV. Highlighting important equipment and tools to protect yourself
When working in an aquatic environment, being fully and effectively equipped with protective devices and tools is extremely important to ensure personal safety.
- Life Jacket: A life jacket is one of the most important pieces of equipment when working on the water’s surface. They provide buoyancy and help workers stay afloat. Life jackets should be thoroughly checked before use to ensure effectiveness.
- Mask: A mask or special breathing apparatus can provide clean air to breathe underwater. This is important in case breathing underwater is necessary.
- Flashlight: A waterproof flashlight is important equipment to provide light in dark underwater environments or in emergencies.
- Line Cutter: A line cutter is a useful tool for cutting ropes, cables, or other materials in case you need to escape a dangerous situation.
- Protective Gear: In addition to life jackets, there is other protective gear such as helmets, gloves, and jackets to protect against harmful elements like sun, wind, or rain.
- Rescue Equipment: In case of an emergency, rescue equipment such as a life raft, rescue buoy, or life ring can be extremely useful to protect yourself and your teammates.
- Troubleshooting Tools: Tools like a rescue hammer, ropes, or life raft inflation devices should also be available to handle emergency situations.
Remember to thoroughly check all equipment before use and regularly during work to ensure its safety and effectiveness. This equipment not only helps protect you but can also be life-saving in emergency situations. You can see more details about occupational safety training content under Decree 44.

V. What you need to know about the underwater environment and how to interact with it
The underwater environment is a mysterious world with diverse marine animals and seabeds. To have a safe and enjoyable experience when working or participating in underwater activities, you need to master the following:
- Understand the Deep Sea: The deep sea is home to thousands of marine species. Before exploring, learn about the types of animals and coral you might encounter. This helps you ensure you do not harm the underwater environment.
- Do Not Interfere: When encountering marine animals, avoid interfering with their lives. Do not touch or try to collect rare marine species. Keep your distance and let them live naturally.
- Protect Coral Reefs: Coral reefs are important habitats for many marine species. Avoid touching or standing on coral reefs to protect their integrity.
- Explore with a Guide: If you want to explore the seabed or participate in activities like scuba diving, hiring a guide is a good choice. They have the knowledge and experience to help you enjoy the experience without harming the environment.
- Clean Up After Exploring: Ensure you do not leave trash underwater or on the beach. The underwater environment is very sensitive and needs to be protected from pollution.
- Master Skills: If you participate in underwater activities, such as scuba diving or surfing, make sure you have mastered the skills and are following safety rules.

VI. Guide to safe diving techniques and risk management
Scuba diving is a wonderful experience, but it also requires preparation and adherence to safety principles.
- Professional Training: If you are a beginner or do not have much diving experience, take a diving course organized by professional centers. This is a good way to learn how to use equipment and basic diving techniques.
- Equipment Check: Before diving, check your equipment thoroughly, including the air tank, wetsuit, mask, and regulator. Ensure that all are working well and regularly maintained.
- Make a Plan: Before each dive, plan the depth you will reach, the expected time underwater, and the dive schedule. Always have a backup plan for bad scenarios.
- Always Have Protective Gear: Ensure you always wear a wetsuit and protective gear such as a mask, backup regulator, and underwater signaling device.
- Risk Management: Master safe diving rules, including risk management and knowing how to respond to emergencies like running out of air or getting lost.
- Adhere to Depth Limits: Adhere to safe depth limits for diving. Do not dive deeper than you are trained or equipped to do.
- Breathing Skills: Master breathing skills and regularly check pressure equalization in your ears as you change depth.
- Visit a Doctor: Before starting or returning to diving after a long time, visit a doctor to ensure you are healthy enough for this activity.
- Dive with a Buddy: Always dive with a buddy and have an experienced buddy if you are a beginner.
