“Natural gas explosion kills nearly 300 at Texas school”

At 3:05 p.m. on March 18, 1937, a Thursday afternoon, the 694 students and 40 teachers in attendance at the Consolidated School were looking forward to the final bell, which was to ring in 10 minutes. Instead, a huge and powerful explosion, which literally blew the roof off of the building, leveled the school. The blast, which came without warning because natural gas had no smell back then, was felt by people 40 miles away and killed most victims instantly. People rushed to the scene to pull out survivors; hundreds of injured students were hauled from the rubble.

“Sunderland explosion: Two injured in gas blast at the house”

Pictures of the damaged house show its roof and part of the front of the property missing, with bricks and debris strewn across the street.

One of the injured men was flown to Newcastle's Royal Victoria Infirmary by the Great North Air Ambulance Service, the other was driven to Sunderland Royal Hospital.

Its chief fire officer Chris Lowther tweeted that "a significant gas explosion" had occurred and search and rescue teams had responded to the incident.

With the consumption of natural gas has risen significantly in winter, the accident risk has risen also. Solving the gas safety problem is imminent. Let RF-star’s ZigBee CC2652P module solution help you away from the gas leakage risk.

RF-star Smart Natural Gas Detector Solution

The following is a simulated scene of the kitchen, which is equipped with a ZigBee gas alarm, a solenoid valve, a gas meter and a gateway to demonstrate the intelligent solution of the gas scene.

Three Realization Scenarios of ZigBee Gas Alarm

• (1) The ZigBee gas alarm detects a high concentration of gas, and an alarm will occur. The gas alarm uploads the alarm information to the cloud platform through the gateway, and the cloud platform controls the solenoid valve to close the valve.
• (2) The ZigBee gas alarm detects a high concentration of gas, and an alarm will occur. The gas alarm actively connects to the solenoid valve through the pre-configured MAC address and notifies the solenoid valve to close the valve.
• (3) The ZigBee gas alarm detects a high concentration of gas, and an alarm will occur. the gas meter is actively connected by the gas alarm through the pre-configured MAC address, the gas meter closes the valve and reports to the cloud platform through NB-IoT.

The above solutions can be achieved by RF-star TI CC2652P ZigBee Module.

RF-BM-2652P2 is a module designed by Rf-star based on TI CC2652P, which supports multiple protocols, including BLE, ZigBee and Thread.

The above gas alarm work topology can also be implemented based on BLE or Thread protocol. The BLE protocol can also realize the interaction with the mobile APP.
