Containment work platform

A worker support apparatus that enables a worker to service an oil well next to a wellhead having a valve tree, comprising:

• a) a platform having an upper floor, a lower floor, multiple corners, and a cellar cavity in between the floors;
• b) the platform having a periphery, a central opening, a plurality of peripheral beams and a plurality of radially extending beams, said plurality of radially extending beams extending in said cellar cavity;
• wherein one or more of said radially extending beams extends from said central opening to one of said peripheral beams;
• wherein one or more of said radially extending beams extends to one of said peripheral beams at a position in between two of said corners;
• each of said radially extending beams has a height that is equal to a majority of a distance between the upper floor and the lower floor;
• c) a plurality of walls having a height of around 3°-6′ attached to the periphery of the platform, said plurality of peripheral beams connecting to said walls above said upper floor, the walls forming a dam around the upper floor and sealing the cellar at the platform periphery;
• d) a drain that enables fluid to drain from the upper floor to the lower floor;
• e) a coupler that occupies the central opening and that spans between the floors, the coupler enabling a connection to be made between the platform and the valve tree, the coupler extending above the upper floor and below the lower floor;
• f) at least two doors in the walls.

• f) a liquid guard that disallows the escape of fluid from the upper and lower floors via the central opening;
• g) at least two doors attached to the walls;
• and
• h) wherein one of said radially extending beams extends to one of said plurality of peripheral beams at a position below said doors.
