Life on the high seas is subject to special safety regulations. Even during the construction phase, fire protection during welding, repair, and maintenance work on a ship is essential. A major fire and the smoke and fumes it would produce puts the entire workforce, and the ship itself, in serious danger. MOBS can be used during a ship's construction phase until a built-in system is permanently in place on the ship, and also if this system is disabled or being maintained.
