Q. Safe conditions and safe acts.
Answer: Playgrounds and outdoor play equipment offer kids fresh air, friends, and exercise. So, it is important to make sure that faulty equipment, improper surfaces, and careless behaviour do not ruin the fun. You can keep the playground entertaining and safe by checking equipment for potential hazards and following some simple safety guidelines.
Q. What are the guidelines for safe conditions and safe acts?
Answer: You must know how to be safe and act responsibly at the playground.
- Never push or roughhouse while on jungle gyms, slides, seesaws, swings, and other equipment.
- Use equipment properly—slide feet first, don’t climb outside guardrails, no standing on swings, etc.
- Make sure that there is enough clearance in front of equipment like slides, swings, etc., and that children do not linger around when equipment is in use.
- Always check to make sure no other children are in the way if they’re going to jump off the equipment and land on both feet with their knees slightly bent.
- Leave bikes, backpacks, and bags away from the equipment and the play area so that no one trips over them.
- Always wear a helmet while cycling/bike riding.
- Never use playground equipment that is wet because moisture makes the surfaces slippery.
- Check playground equipment in the summertime. It can become uncomfortably or even dangerously hot, especially metal slides, handrails, and steps. So use good judgement—if the equipment feels hot to the touch, it is probably not safe or fun to play on. Contact burns can occur within seconds.
- Wear clothes that do not have drawstrings or cords. Drawstrings, purses, and necklaces could get caught on equipment and accidentally strangle a child.
Q. What are the key things to keep in mind to make safe ground conditions?
Answer: The most important factors in evaluating the safety of any playground are proper surface, design and spacing, and equipment inspection and maintenance. A proper playground surface is one of the most important factors in reducing injuries—and the severity of injuries—that occur when children fall from equipment.
Q. Why is it important to know the correct ways to perform the exercises?
Answer: The proper exercise techniques are important for maximising benefits and minimising risks. The benefits of correct exercise technique are:
- Correct exercise technique reduces the risk of strain.
- Correct exercise promotes symmetrical strength and flexibility.
- It enhances strength, endurance, and coordination.
- It helps for better oxygen flow and cardiovascular function.
Q. First aid and medical aid.
Answer: First aid is the emergency care given to the injured or suddenly ill person at the scene by using readily available material. Proper first aid prevents accidents and injuries from becoming tragedies. Medical aid is the treatment given by, or under the supervision of, a physician at a medical facility. Medical care is given by qualified professionals.
Q. Sprain and strain.
Answer: A sprain is a stretch or tear of a ligament. Ligaments are tissues that stabilise and support the body’s joints. A strain is a twist, pull, or tear of a muscle or tendon.
