Turnarounds often require an increased number of workers who use gas detection to avoid hazards including oxygen deficiency and combustible or toxic gases. To meet this need, companies must decide whether to rent or buy portable gas detection equipment. Here are some options to consider.
Renting equipment
Not all gas detector rental programs offer the same benefits. Be sure to scope out the project and ask the right questions:
- When does the rental period start, and when does it end? Some rental companies start the clock the day the equipment leaves their facilities; others start it the day it is received.
- What is included with the gas detectors? E.g., if you are getting a monitor with a rechargeable battery, ask if the charger will be included.
- What gas detector accessories would be ideal for a given application? Ask the rental company about accessories that might make the job easier.
- Do I need to pay for sensors that fail while in use? Some rental companies make up the internal expenses of maintaining their rental fleet by charging customers for sensors that fail while in use, even if the sensors fail due to normal use.
- Are the monitors pre-calibrated? Ask to have calibration certificates provided with each rental unit.
Disposable detectors
There are some attractive, low-cost disposable gas detectors available on the market. Before purchasing disposable units, consider the tax factors and disposal costs. Purchasing gas detection equipment is considered a capital expense and must be treated as such at tax time. The entire expense of that purchase cannot be deducted during the year in which it was purchased. The capital costs are amortized or depreciated over the useful life of the piece of equipment. When it comes to disposal, the typical cost of a single gas monitor is upward of $75 each. Batteries, boards and sensors must all be disposed of separately. This involves labor related to disassembly, collection and paperwork, as well as packaging costs and disposal fees.
Expanding your fleet
Another option is to purchase non-disposable gas detectors to be added to your typical fleet of gas detectors. In this case, companies assume responsibility internally for the maintenance of the instruments. Here are a few things to consider before purchasing extra gas detectors:
- Labor costs. Bump tests, calibrations and sensor replacements are some of the time-intensive maintenance tasks associated with portable gas monitors.
- Service training. To service the instruments, both time and money are required to train employees to do so.
- Purchasing parts. With a purchase comes the actual cost of parts and pieces, plus taxes.
There are many options to ensure that an increased workforce during a shutdown is properly protected from hazardous gases. Renting gas detection equipment can be the most cost-effective and efficient way to keep workers safe. Consider the unseen costs of purchasing gas monitors versus renting them for short-term needs such as turnarounds.
