For the best answers, search on this site shorturl.im/avvut As a member of the National Ski Patrol (US) I do advocate the wearing of snowsports helmets. However I do not support mandatory helmet use. Tens of thousands of people have skied or snowboarded for years without the slightest injury to the head. It should be up to the skier or rider. I wear one 90% of the time, but there are days I don't wish to wear one and I should have that right. We also do not need to tie up the government and legislative process passing laws that effect only a small part of the population. If anything, it should be a policy reserved for the resorts to impose if they so choose to do so. If it were a law, it would mean additional training for Ski Patrol as now we would have to be trained in law enforcement, or there would have to be cops on skis at the resorts. There is no way to enforce this in the backcountry or at a private ski area open only to club members. Educate, don't legislate. There are plenty of organizations already advocating helmet use and snowsports safety. Ski areas, by and large endorse these advocacy groups. Ski Instructors, Ski Patrol members, and on-snow employees of the resorts should set the example and wear a helmet. Parents and novice skiers should receive information about helmet safety when purchasing a ski ticket. Helmet safety should be covered in lessons. These things I support, but not legislation.
I have no idea what you are talking about. The fritz helmet is kevlar and the other POS is steel.hardly superior Edit: The prime overriding purpose of a helmet is to protect your melon.NOT cooking. And with the advent of combat rations no one cooks in their helmet anymore.IF they ever did as expsoing even a steel helmet to heat would screw with it's tempered properties.
I can only guess that if your beloved Adrian helmet was a superior design, someone, somewhere, might still be using it.
A.H2SO4 + 2KOH K2SO4 + H2O B. CH4 + 2O2 CO2 + 2H2O C. Zn + CuSO4 ZnSO4 + Cu D. Ni + CuSO4 NiSO4 + Cu E. 2C4H10 +13O2 8CO2 + 10H2O
a) H+ (aq) + OH- (aq) -- H2O (l) b) CH4 (g) + 2O2 (g) -- CO2 (g) + 2H2O (l) c) Zn (s) + Cu2+(aq) -- Zn2+ (aq) + Cu (s) d) Ni (s) + Cu2+ (aq) -- Ni2+ (aq) + Cu (s) e) 2C4H10 (g) + 13O2 (g) - 8CO2 (g) + 10H2O (l) b and e has no ionic equations; they're in molecular
