M-CODED Releases Focus on Safety Discussions

The Marine Construction, Offshore, Diving, Energy, and Dredging Committee is pleased to announce the release of a new Focus on Safety topic, available for use in safety meetings and toolbox talks.

Working in marine construction and heavy equipment environments presents a wide range of hazards that require constant awareness, clear communication, and disciplined safety practices. From crane signaling and heavy machinery operation to emergency response and vessel safety, each task carries its own risks that can escalate quickly if not properly managed. Please review the information below for practical guidance and essential reminders to help crews recognize hazards, prevent incidents, and respond effectively when challenges arise.

Basic Hand and Voice Crane Signaling

Not having basic hand and voice crane signaling creates a high-risk environment where miscommunication can quickly lead to accidents. Crane operators often rely on clear, standardized signals to coordinate movements with ground personnel, especially when visibility is limited or noise levels are high.


Dozer Safety

Dozers can be dangerous simply because they’re so big and powerful, and the operator can’t always see everything around them. It’s easy for someone on the ground to end up in a blind spot, especially when the machine is backing up or turning. Working on rough or uneven ground can also make a dozer unstable and increase the risk of tipping over.


Excavator -Track Hoe

Excavators, or track hoes, can be dangerous because of their powerful movements and wide swing radius. It’s easy for someone on the ground to get caught off guard if they step into the machine’s swing area or blind spots. The bucket and arm can move quickly and with great force, posing a risk of being struck or pinned.


Helpful Tips for a Collision While on a Barge

When you find yourself on a stationary barge with another vessel rapidly approaching, the situation can be both alarming and dangerous. However, staying calm and following a set of structured steps can greatly increase your chances of avoiding disaster. Here are some helpful tips to navigate this perilous scenario.


Helpful Tips for Man Overboard

Practical guidance for conducting a Man Overboard safety meeting, including key response steps, prevention tips, and discussion points to help teams stay prepared and respond quickly in an emergency.


Helpful Tips for Managing an Underwater Utility Strike

Striking an underwater utility can lead to significant risks, including environmental damage, safety hazards, and costly repairs. It is crucial to understand these risks and plan accordingly to mitigate them.


Helpful Tips for Overhead Utility Strike

Overhead utility strikes in marine construction pose serious risks, including electrocution, equipment damage, and project delays. Workers must be aware of the location of power lines and other overhead utilities, maintain safe clearances, and follow proper signaling and lifting procedures.


Helpful Tips to Clean a Spill When Working on a Barge

Quick, practical guidance for safely cleaning spills while working on a barge, including containment steps, hazard awareness, and best practices to protect workers and the environment.

Helpful Tips to Extinguish a Fire Safely on a Barge

Straightforward, actionable guidance for safely putting out fires on a barge, including identifying fire types, using the correct extinguisher, and following key response steps to safeguard crew and equipment.

Marine Access

Marine access hazards arise when improper or unsecured methods are used to board or exit vessels, increasing the risk of slips, falls, or sudden movement between structures. Using unstable access such as tires or fenders, unsecured or damaged gangways, unguarded gaps, and metal gangways that can shift on metal decks can lead to serious injury—especially with changing tides, currents, or vessel movement—making proper equipment selection, secure installation, and frequent inspection critical for safety.


Overhead Load Hazards

Overhead loads present serious safety hazards because they combine gravity, instability, and limited reaction time. If a suspended load shifts, drops, or is improperly secured, it can cause severe injury or fatality to anyone beneath or nearby. Even small objects can become dangerous when falling from height, and larger loads—such as those moved by cranes or hoists—can swing unpredictably due to momentum or environmental factors like wind.


Raise and Lower Spuds

Spuds present serious hazards due to the high forces and moving equipment involved during setting and pulling operations. Risks include pinch and crush points, sudden vessel movement, spud failure or slippage, and structural damage to the barge or seabed.

Seamanship

Seamanship is the practice of operating a vessel safely, responsibly, and courteously under all conditions. It includes wearing life jackets and ensuring there is enough on board for everyone, checking the weather before departure, and minimizing wakes to protect other boaters and shorelines. Good seamanship requires maintaining a safe, controlled speed, following no‑wake and speed‑restricted zones, avoiding overtaking in narrow channels or marinas, and staying alert in high‑traffic or shipping areas where larger vessels may have limited visibility.


Tender Boat Safety

Tender boat safety requires that only trained and authorized personnel operate tender boats, with each trip planned, approved, and conducted according to weather and water conditions while wearing required PPE. Operators must inspect the vessel, engine, and life‑saving equipment before every trip, ensure safe footing and balance on deck, maintain clear communication, keep clear of towing lines, and guard all deck openings to prevent slips, trips, and injuries.


Working Over Water

Working overwater hazards include the risk of falling into the water, being crushed between vessels or barges, becoming trapped underneath, or drowning due to improperly worn PFDs. Additional dangers include slippery surfaces, moving equipment, waves, poor visibility, and wildlife, all of which increase the likelihood of serious injury or fatality if proper precautions are not followed.
