Question 395

Emergency Decon

Answer 395

Gold emergency Decon is to remove the threatening contaminant from the victim as quickly as possible – there is no regard for the environment or property protection. Emergency Decon may be necessary for both victims and rescuers. If either is contaminated, individuals must remove their clothing or PPE and wash quickly. Victims may need immediate medical treatment, and they cannot wait for the establishment of a formal decontamination corridor. Here are some reasons for emergency Decon -Failure of PPE. -Accidental contamination of emergency responders. -Immediate medical attention required by emergency workers or victims in the hot zone.

Question 396

Non-intervention

Answer 411

Using this bass response philosophy will help the incident commander determine if non-intervention is the correct option. Based on the conditions on scene, it may not be possible to approach a container or stop a leak or get close enough to a product to attempt to containment.Safety must always be the first priority in any response operation, including Responder safety and effectiveness. Public safety. Position and vulnerability of communities of wind and downwind. Environmental health. Long term and short term affects of material release

Question 412

Defensive operations

Answer 412

Defensive operations mean that the emergency response personnel will work to can find the product release and limit the physical size of the release area.Environmental protection is a special consideration because the hazard product can be released directly or indirectly into the air, surface water, ground water, or onto the soil.Depending on the area effective, various confinement methods may be available to help restrict the spread of the product.

Question 429

Container cracks

Answer 429

Cracks in base metal, no matter how small or a reason for concern. If the base metal of a container is cracked off load a container as soon as possible. When a dent, score, or gouge accompanies a crack, emergency responder should stabilize the tank without moving the container. Technician should also consider a cracked pressurize container critical and likely to fail at the depth of the fracture cannot be determined

Question 430

Dents in containers

Answer 430

That’s that run parallel to the long access of a container can be critical based on the containers manufacture date. Pressurize tags constructed before 1966 of either E 212 or B515 grade still are considered to be critical condition and likely to fail if they have a den of less than 4 inches. The same is true for pressurize container build during or after 1966 that uses TC – 128 Steele and has a dent with an inside radius of less than 2inches 

Question 431

Large container dents

Answer 431

Massive Dents in the head of the Tech are generally not serious unless gouges or cracks are present with the dent.

Question 432

Small container dents

Answer 432

Small dent in the head of the container tank not exceeding 12 inches in diameter, and conjunction with cold work in the bottom of the dent, are marginal if they show a radius of curvature less than 4 inches. Small dents in other places other than the head of the tag may not be critical unless they are also associated with gouges and cracks.

Question 433

Scores and gouges

Answer 433

Not as critical as a crack in the base metal but they must be monitored, Score or gouge is not critical with a cross is the same as long as the base metal is still in tact

Question 444

Portable pumps

Answer 444

Portable pumps coming a variety of sizes and I used to move liquids. Please pass me the electric, gasoline, diesel, PTO power takeoff, water, or air powered. Select the type And size based on the type of product being transferred, the capacity of the receiving container, and the left and flow capacity is needed at the scene.

Question 445

Pressure differential pumps

Answer 445

Used to create pressure differential between two tanks to transfer vapors and gases. A vapor compressor creates a positive pressure differential to move the product by pulling vapors from the receiving tank, compressing them, and forcing them into damaged tank car.The increase pressure in the damage tank pushes the product into the receiving tank. Responded and consider how much pressure the damage container can take pressure differential pumps may be used in tandem with portable pumps to increase the speed and efficiency of the transfer of product.
