1. In the process of performing dangerous operations in limited space, ventilation and ventilation should be strengthened to maintain the necessary number of measurements or continuous testing.
2. The lighting used in the operation should use the safety light of 12 volts or less, and the hand-held power tool exceeding the safe voltage must be equipped with the leakage protector according to the regulations.
3. When detecting the presence of harmful gases or flammable gases, the inspectors should use hazardous gas detection instruments, combustible gas testers, and other equipment for testing.
4. Inspectors wear isolated respirator and use of oxygen respirator is forbidden;
5. Existence of combustible gas or flammable dust on the site, all testing equipment, power tools, lighting fixtures, etc., must use explosion-proof products that meet the requirements of the “Electrical Device Design Specification for Explosive and Fire Hazardous Environmentsâ€.
6, in the dangerous workplace, must take adequate ventilation and ventilation measures, it is strictly forbidden to use pure oxygen for ventilation.
7. For places where explosion-proof and anti-oxidation can not adopt ventilation and ventilation measures or are not easily ventilated by operating environment, operators must equip and use isolated breathing apparatus such as air respirator or hose mask.
8. The operator should accurately count the number of people before entering and leaving the dangerous space in the limited space.
9. In order to enter dangerous space operations in limited space, operators and guardians should provide clear contact signals in advance.
10. When an oxygen deficiency is detected or an instrument detects an alarm, the dangerous operation must be stopped immediately. The personnel at the operating point should leave the job site quickly.
11. It is forbidden for unrelated personnel to enter dangerous space in limited space, and warning signs should be set up at eye-catching places.
12. Rescue equipment, such as breathing apparatus, ladders, ropes, and other necessary appliances and equipment must be provided in a limited-space dangerous workplace to rescue workers in extraordinary circumstances.
13. When operating carbon dioxide fire extinguishers in poorly ventilated workplaces such as basements, containers, etc., fire extinguishers should be placed firmly and prohibited from starting accidentally to prevent accidental release of carbon dioxide, and clear signs should be placed where fire extinguishers are placed. 17. When operating personnel inside the closed equipment (such as oil tanks, reaction towers, storage tanks, boilers, etc.) connected to the transmission pipeline, they must close the valves tightly, install blind plates, and set a sign prohibiting start-up in prominent places.
Virus Specimen Collection Tube
Features
1. Medical grade polypropylene material, high transparency, high sealing and low temperature resistance;
2. With 6ml&10ml two specifications, the cone bottom can stand;
3. The thread structure design of the pipe cover ensures high sealing performance; the pipe cover has no O-ring external rotation design to reduce sample contamination caused by operation and storage;
4. It can cooperate with the sampling swab to perform the functions of collecting and transporting multiple types of samples such as viruses and microorganisms.
Applications
Used for the collection and transportation of clinical influenza, avian influenza, hand-foot-mouth disease, measles and other virus specimens, as well as mycoplasma, ureaplasma, chlamydia and other specimens.
Mixed sample tubes hold more swab heads, so the retention fluid capacity is often larger. For example, single swab retention solution is generally 3ml, 10 and 1 sample tube retention solution is generally 6ml, 20 and 1 retention solution is 10-12ml. The same amount of viral nucleic acid (e.g. 300copies) is stored in 3ml, 6ml, and 12ml copies in concentrations of 100copies/ml, 50copies/ml, and 25copies/ml respectively. Obviously, the greater the number of mixed tests, the lower the virus concentration, the higher the detection sensitivity will be required.
The more the number of mixed tests is, the contact surface between the swab head, the preservation solution and the tube wall will be doubled, which will lead to the increased probability of viral nucleic acid adsorption on other swab heads or tube wall. These factors all lead to higher requirements for system sensitivity.
