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). benzene, toluene, vinyl chloride, fluorine, hydrogen fluoride, sulphur oxides, chloroacetic acid, aldehydes, mixtures of inorganic acids, and organic substances, mercury vapors, radioactive iodine, organic compounds of iodine (Iodomethane, 129, 131), radioactive particles, etc.Respiratory protective masks (usually called respirators) are used whenever airborne contaminants are present and cannot be economically controlled by engineering means or administrative controls. The filter canister in connection with a suitable respirator or PAPR provides protection against solid and liquid particles, pepper spray (OC), smoke-producing substances, radioactive particles, bacteria and rickettsia, fungi, toxins, viruses, riot control agents (lachrymators, sternutators, vomiting agents), blister agents (vesicants), choking agents, blood agents, nerve agents, incapacitants, herbicides, pesticides, and TIC, such as bromoacetone, CS, CR, CN, CNC, CNS, CA substances, organic compounds of arsenic - diphenyldichlorarsine - CLARK I (DA), diphenylcyanoarsine - CLARK II (DC), adamsite (DM), diphenyldichlorarsine (DA), ethyldichlorarsine (ED), methyldichlorarsine (MD), mustard gas (H), sulphur mustard gas (HD), T-mustard gas, Q-mustard gas, nitrogen mustard gases (HN1, HN2, HN3), lewisite (L), mixed mustard gas (H-L), phosgene oxime (CX), phosgene (CG), diphosgene(DP), chloropicrin (PS), hydrogen cyanide (AC), cyanogen chloride (CK), arsine (SA), G-agents: sarin (GB), cyclosarin (GF), soman (GD), tabun (GA), IVA (GV), V-agents: VX, VR, VE, VG (amiton), VM and toxic industrial chemicals such as: fumes of organic or inorganic acids, hydroxides, organic solvents with a boiling point above 65° C, ammonia, amines, inorganic and acid gases, agricultural chemical combustion gases, other toxic substances, e.g. EN 1) NBC-77 SOF 260 99.999 >99.999Ģ) The filter was tested on dolomite dust cloggingģ) Radioactive iodine and its organic compound - methyliodide¹³¹ acc.
