How many time is normal mask life ?


it depends on the quality of the mask and it depends on how you stored it (if you leaved it at sunlight, if you washed it thoroughly after using it in the sea...)
i have a mid quality mask Mares mask, i have been using about 20 times for snorkeling, then i used it to take diving certifications in pool, then i used it for about other 20 dives in the sea... i always stored it in a dark bag (the mask is now about 8 years old)
you can check if you mask is still in good shape, and the silicone has not worn out, in this simple way: just put the mask on your face without straps.. remove all the air inside the mask by inhaling with your nose.. then look at your feet (keep inhaling): if the mask remains on your face you can keep using it

It sounds as if there is liquid rolling around in my ventilation system. Any technical reason for this?


Ventilation system is also the heating system which is filled with water. Water is pumped around by the water pump. Sounds like you have an air lock.

What was a gas mask?


The gas mask is a mask used to protect the user from inhaling airborne pollutants and toxic gasses. The mask forms a sealed cover over the nose and mouth, but may also cover the eyes and other vulnerable soft tissues of the face. Some gas masks are also respirators, though the word gas mask is often used to refer to military equipment (e.g. field protective mask). The user of the gas mask is not protected from gas that the skin can absorb. Most gas mask filters will last around 24 hours in a nuclear biological chemical (NBC) situation.
Airborne toxic materials may be gaseous (for example sulfur mustard and chlorine gas used in World War I) or particulates (such as many biological agents developed for weapons such as bacteria, viruses, and toxins). Many gas masks include protection from both types. Gas masks are used in construction to protect against welding fumes, in deconstruction to protect against asbestos or other hazardous particles, and in the chemical industry when handling hazardous materials, as in making repairs to leaking equipment or cleaning up after spills; workers have usually issued gas masks as a precaution against leaks.
During demonstrations and protests where tear gas or CS-gas is employed by riot police, gas masks are commonly used by police and demonstrators alike. Aside from serving their functional purposes, gas masks are also used as emblems in industrial music, with the most notable example, the subgenre of drum and bass called Neurofunk. These emblems are used by graffiti taggers because the mask protects them from the paint canister's toxic fumes, and by urban explorers venturing into environments where hazardous materials, such as asbestos, may be present.

Hear water sounds in dashboard, but no water comes out


If you cannot detect any water coming out under the dash, or trickling down the floorboard under the carpet, then it is most likely you have an air bubble in your heater core.

This by itself isn't harmful, and if you can stand it, drive around with the heater full on to see if this will get rid of the air.

If it won't, then try this strange sounding trick. Park the car on the very steepest grade you can find, nose up. This will put the radiator cap higher than your in-dash heater core. Then remove the radiator cap, turn the heater or climate control to full heat, and run the motor until it reaches operating temperature. Hopefully you will see a big burp of air emerge!

My mask is leaking at the inner seam


I would clean the area really well and use a silicone glue. It's available at Home Depot, Ace, etc. and provides a flexible, water proof seal. Enjoy the reefs!

Been siting for awhile,can't get gas to engine


This is going to sound strange but sometimes when a vehicle sits the gas drains back into the tank. This happens when there is an air leak in fuel system (lines, fuel filter, fittings in the system, etc). Place a short length of hose into the gas tank filler opening. Prepare to blow into the hose while sealing the opening around the hose and the filler neck. You can seal it with tape or just by holding a plastic bag tightly over the opening and around the hose. Blow in slowly and steadly. You want to pressurize the system and then hold the pressure to force the gas thru the fuel lines, fuel filter, etc. You want to inhale thru your nose and exhale into the hose just enough to pressurize the system. You can then exhale thru your nose as long as you hold the pressure in the hose (stick your tongue over the hose end to seal it). Don't breathe in from your mouth or you will be hating things. When releasing pressure from the hose do so gently or the gas will slosh back on you. You can have someone crank the engine while you are pressurizing the fuel system. You are just trying to move the fule that much closer to the carbs so you can get her running. Another option is to pour some gas down the car and try starting the vehicle. It will run for a short time and allow the fuel pump to pressurize the system. .

How to choose a scuba mask


"The shape of the scuba mask and the silicone skirt on the mask must conform to the shape of your face to provide you with a comfortable fit. Ensuring the silicone skirt is a high-grade, flexible silicone can help to ensure the scuba mask conforms to the shape of your face and the long life of your scuba mask. Some people are allergic to different types of rubber, if you have an allergy to rubber, be sure to choose a silicone scuba mask because silicone is hypoallergenic. Always talk to your scuba diving gear retailer about the alternatives available to you. When trying on scuba masks you will notice the different shapes of the nose pockets. The nose pocket protects and cushions your nose, helps to keep your scuba mask from fogging during a dive and helps you to maintain equalization. Ensure the size and shape of your nose pocket is comfortable; not too tight and not too large. This will improve not only the comfort of your scuba mask, but your ability to purge your mask efficiently. There are increasingly different styles of scuba mask straps on the market. You may like the factory issue strap on your scuba mask or you may want to purchase a separate strap. Scuba mask straps are available in a single strap or a double strap design. The single strap should wrap around the centre of the back of your head. The benefit of the double strap is that you can position the top strap on the upper part of your head and the bottom strap on the lower part of your head to offer extra stability and comfort. Most scuba mask straps are rubber or silicone and fasten with a post-hole belt enclosure. Newer scuba masks offer a slide-lock type enclosure, which allows you to adjust the scuba mask quickly and easily when wearing the mask. Scuba masks are constantly improving. If you wear prescription glasses or contact lenses on a daily basis you can purchase a scuba mask without having to wear your glasses or contact lenses under your mask. Many manufacturers will create custom scuba masks which include your prescription in the front lens. A good sign you have chosen the right scuba mask for your face is when the mask stays on your face comfortably without using the straps to hold it in place. You should try this simple test with each scuba mask you try on for the first time: See our choices for scuba masks 1. Place the scuba mask over your eyes and mouth ensuring the mask is in the correct position. 2. Take a quick, light breath in through your nose and immediately start to breathe through your mouth as if you are scuba diving. This will create a slight suction between the scuba mask and your face. The scuba mask should stay on your face. If you must push the scuba mask against your face, or inhale repeatedly to help the mask stay on your face, the mask is not a good fit. 3. Keep the scuba mask on your face for approximately one minute. This will help you to determine how tight the seal is and how comfortable the mask is on your face. 4. Exhale gently through your nose to release the seal on your scuba mask and remove the mask from your face. There should be no mark on your face from the scuba mask. If there is a red line around your face from the seal of the mask, the seal was too tight or the mask is not the proper size for your face. Try the test a second time. If you still have a red mark on your face after you remove the mask, you need to continue your search for a scuba mask. Remember, a good scuba mask is one that's comfortable, doesn't leak and is easy to use."
