After that, other energy- transforming mechanisms are necessary to replenish the ATP supply. There is enough creatine phosphate present to keep the muscle working for up to 2 min. When the muscle starts working there is enough ATP in the muscles to sustain the work for 0.5 sec. There is also another energy-rich compound in the muscles called creatine phosphate that can act to replenish the ATP supply extremely quickly. It is important, therefore, to replenish the ATP supply as quickly as possible in order to maintain muscular work. When the supply of ATP is exhausted, muscle activity ceases.

This energy comes from an energy storage molecule called ATP (adenosine triphosphate). Respirators may appear to be rather simple, but they can interfere with : Understanding possible physiological and psychological effects of respirator wear requires a thorough understanding of the wearer and possible respirator effects. Quantitative assessments of these burdens have been made so that respirator design trade-offs, wearer usages, and regulations can accommodate the needs of the wearer. These burdens can even be severe enough to cause life-threatening conditions if not ameliorated. These can interfere with task performances and reduce work efficiency. Īlthough the protective mechanisms of respirators are largely physical and sometimes chemical, wearing respirators come with a host of physiological and psychological burdens. The threats may be from gases, vapors, dusts, and particulates of various sizes, including aerosols. They are used by personnel in homes, industry, agriculture, mines, emergency first responses, medicine, and the military wherever airborne contamination is a possible threat.

Respirators come in many forms, including popular filtering facepiece respirators (FFRs), one-quarter, one-half, and full facepiece masks, and filtering air-purifying respirators (APR), air-supplied respirators, blower powered air-purifying respirators (PAPR), and self-contained breathing apparatus (SCBA).

This was another warning I have issued here and elsewhere that wasn't heeded.Respiratory protective masks (usually called respirators) are used whenever airborne contaminants are present and cannot be economically controlled by engineering means or administrative controls. It can be extremely counter-productive because it causes people to take risks with inadequate or improperly-worn PPE when they would have otherwise avoided the hazard.

Just as I said it would.Īlso, you have to be careful with the 'something is better than nothing' mindset. Most of the N95-P100 mask failures were likewise due to improper fit, or improper use allowing contaminants to bypass the filter medium. Cloth and paper masks didn't help infection rates because of contaminant bypass, poor fit, and improper use. Oddly enough, things turned out EXACTLY as I explained they would. I tried to explain at the start of the pandemic the drawbacks and potential pitfalls of using disposable respirators and why cloth and paper masks wouldn't work, but I was ignored and told that I didn't know what I was talking about. The reason masks 'didn't work' was because federal, state, and local governments stuck millions of untrained people with faces of all shapes and sizes into masks and respirators with no fit testing and no training. There are some that simply cannot be filtered (the radioactive noble gasses), but they are generally not a major source of internal contamination and exposure.Ĭlick to expand.I'm not calling you out specifically here SeabeeOnce, just venting. Ideally, a full-face respirator with a CBRN-rated filter will filter most but not all of the materials. 'Fallout' or really the gas and vapor plume from a nuclear reactor meltdown is a different animal and requires more substantial protection. Ideally, you want CBRN filters, but P100 and N95 masks will work well too. Just as with COVID, you can have some bypass with surgical or cloth masks and disposable respirators need to fit and be worn properly. There may be some infiltration, but testing from the days of the atomic era showed that inhalation dose was not significant when compared to the dose produced by exposure to fallout outside the body.Īs far as what masks work, well, everything from dust masks to full-on full-face respirators will work. The fallout particulates from nuclear weapon fallout that reach ground level are fairly large (sand-like) and will not stay suspended in the air long enough to flow into buildings.
