The Mahtomedi Lacrosse Club officially became the Mahtomedi Youth Lacrosse Association in 2008 continuing its volunteer support of High School and Middle School level Youth Lacrosse. In Spring, 2006, the Minnesota High School League voted in Boys Lacr
Prior to the start of a contest, the host school is responsible for determining whether or not the conditions present a threat to the safety of participants and spectators, and will determine whether or not the contest will begin. Once the contest begins, the officials have the authority to postpone or suspend a contest due to unsafe weather conditions -- that decision may not be over-ruled. School officials also still have this authority. The Superintendent or his/her designee may over-rule an official and suspend or postpone a contest once it has begun. In other words, once a contest has begun either the officials or school authorities may postpone or suspend a contest, and cannot be over-ruled by the other party. When in doubt, error on the side of safety.
While lightning on the horizon should warn of potential danger, lightning associated with thunder or thunder alone means that there is immediate danger to athletes, officials, and spectators. The adage — "If you can hear it, clear it." — should be used to make decisions to postpone or cancel the activity. Lightning can strike 10 miles ahead of or behind the storm front and thunderhead clouds.
When considering resumption of an athletic activity, the MSHSL recommends that everyone should wait at least 30 minutes after the last flash of lighting or sound of thunder before returning to the field or activity.
Additional lightning-safety guidelines have been developed with the assistance of the National Severe Storms Laboratory (NSSL), and are listed below:
As a minimum, NSSL staff strongly recommend that by the time the monitor obtains a flash-to-bang count of 30 seconds (equivalent to six miles), all individuals should have left the athletics site and reached a safe structure or location. Athletic events may need to be terminated.
The existence of blue sky and the absence of rain are not protection from lightning. Lightning can, and does, strike as far as 10 miles away from the rain shaft. It does not have to be raining for lightning to strike
If no safe structure or location is within a reasonable distance, find a thick grove of small trees surrounded by taller trees or a dry ditch. Assume a crouched position on the ground with only the balls of the feet touching the ground, wrap your arms around your knees and lower your head. Minimize contact with the ground, because lightning current often enters a victim through the ground rather than by a direct overhead strike. MINIMIZE YOUR BODY'S SURFACE AREA, AND MINIMIZE CONTACT WITH THE GROUND! DO NOT LIE FLAT! If unable to reach safe shelter, stay away from the tallest trees or objects (such as light poles or flag poles), metal objects (such as fences or bleachers), individual trees, standing pools of water, and open fields. Avoid being the highest object in a field. Do not take shelter under a single, tall tree.
A person who feels his or her hair stand on end, or skin tingle should immediately crouch, as described in item 3.
Avoid using the telephone, except in emergency situations. People have been struck by lighting while using a land-line telephone. A cellular phone or a portable remote phone is a safe alternative to land-line phones, if the person and the antenna are located within a safe structure or location, and if all other precautions are followed.
People who have been struck by lightning do not carry an electrical charge. Therefore, cardiopulmonary resuscitation (CPR) is safe for the responder. If possible, an injured person should be moved to a safer location before starting CPR. Lightning-strike victims who show signs of cardiac or respiratory arrest need emergency help quickly. Prompt, aggressive CPR has been highly effective for the survival of victims of lightning.
Using the heat guidelines
The heat stress graph is designed to give a competition safety estimate in hot, humid conditions. It is most relevant for long distance running and prolonged high intensity events like soccer, football, and tennis. It should be applied to practices and games.
Using a weather radio or local radio station, collect the air temperature and relative humidity data every hour during the event and plot it on the relative humidity vs air temperature graph. In the late spring and summer months on bright sunny days a correction factor of up to 5 degrees Fahrenheit should be added to the air temperature from to . This should be plotted as a bar rather than a single point to give and estimate of maximum and minimum heat stress.
The decision to cancel or postpone an event should be made when the heat stress moves into the danger range. Although competition can be continued in the other ranges for increased heat stress risk, coaches and athletes should be aware that hypothermia and exertional heat stroke could occur in the lower risk ranges. Track and cross country runners should stay out of the heat between events and stay well hydrated. A rest break should be provided in activities that require continuous activity like soccer and tennis.
