In summary there appears to be at least 18 gun incidents in, or around, schools between 1st January and 14th February 2018. They are not all of the "mass shooting" variety one might expect from the headlines but they have certainly all involved the accidental or intentional letting off of a firearm.
A few notes
I count 17, not 18 The 18th has been found (H/...
The BIC FAQ says the hole in the cap is to prevent children from choking to death.
It was quoted in the question:
The reason that some BIC® pens have a hole in their cap is to prevent the cap from completely obstructing the airway if accidently inhaled. This is requested by the international safety standards ISO11540, except for in cases where the cap is ...
Q Has a virus ever escaped a high-level virus lab?
Yes, depending on definitions.
How deadly pathogens have escaped the lab — over and over again
Most appropriate candidates for an inappropriately cherry picking and restrictive reading of the claim in question:

Yes, because the safety systems that are required for furnaces and water heaters are not standard on stoves and ovens.
Conventional gas-burning furnaces and hot water heaters include two design elements to prevent build-up of carbon monoxide (poison hazard) and natural gas (explosion hazard) inside the house:
A flame sensor checks if the gas is burning. If ...
It depends on what you classify as 'school shooting' and most people would consider this number too high.
You can find an overview over 17 incidents (together with news sources) at:
The list include all gun-related incidents near or in schools like:

Some studies came to the conclusion that bare knuckle boxing may be safer because people punch harder with gloves. This was also attributed to it being painful to punch really hard with just your fists.
Here's a good summary of the studies:
Smith and Smith et al. found that the boxing and karate gloves were not particularly effective in preventing ...
Unlike seatbelts found in cars, a seatbelt on an airplane isn't there to save you if the plane slams front first into the ground or is hit by a missile.
It's there to keep you safe in the event the plane makes a sudden move or has a minor accident. This commonly happens when flying through turbulence. Sudden movements could also happen during a bad ...
It's not just your culture. Advice from the US National Weather Service includes:

Banana peel hazards

The banana peel fall: It"s a myth […] Contrary to comedic genius, […] a single peel isn't a guaranteed fall magnet.
If the physics behind this gag is not as promising, then why invent such a comedic device?

Germany is an interesting case to study this, as they have stretches of highway with and without speed limits. In a study done in the state of Brandenburg, the effect of putting a speed limit on stretches of highway has been studied by comparing the accident statistics before and after the new limit.
On two stretches the speed limit was changed from no limit ...
There was extensive news coverage of this, which eventually points back to this ABC News report from June 1st, 2015. The report references an internal government report, which is not published on the TSA's website with other public or partially redacted reports, at least at this time.
The news story states "undercover investigators were ...
As well as personal experience from eating onions that were cut not on the same day. From the National Onion Association:
Leftover Onion and Cut Onion
Q: Are cut onions or leftover onions poisonous?
A: When handled properly, cut onions are not poisonous. After being cut, onions can be stored in the refrigerator in a sealed container for up to 7 days.
This answer is making use of Daniel R Hicks' links in the comments of the question.
Donald Trump's tweet's phrasing "Since taking office I have been very strict on Commercial Aviation." is, perhaps typically, not very precise. Asked about details, the White House released a statement quoted by factcheck.org:

The New Scientist calculated the number of deaths per kilowatt-hour question based on the data from International Atomic Energy Agency in 2011.
According to the New Scientist:
The agency examined the life cycle of each fuel from extraction to post-use and included deaths from accidents as well as long-term exposure to emissions or radiation.
Per mile driven, are motorcycle riders more likely to die, more likely to get in an accident, or more likely to get in a severe accident, than the average driver of a four-wheel car?

According to the U.S. National Highway Traffic Safety Administration (NHTSA), in 2006, 13.10 cars out of ...
This is a thorny question, both because it is a politicized issue, and because the effects of cannabis use while driving are less well studied than the effects of alcohol, and appear to include a number of confounding factors.
Overall, my survey of the literature suggests that there are two questions, which have (surprisingly) different answers:
As a rider myself I'm sure there's a lot of different opinions but let me answer a few points here.
"motorcycles have to be extra loud so that people in cars take more notice of them"
Is not true. If anything, manufacturers try to make bikes quieter, more fuel efficient and more eco-friendly. For example, Harley Davison, a company know for gas-...

It's not a bad idea, but tuna cans, and most other cans, are packed in boxes or wrapped in plastic at the production line and not opened until they reach the store.
The greater concern is probably all the humans who handled the can. Humans who carry disease communicable to other humans. And it isn't limited to tuna. Wash your hands.
This seems to be a twist ...
There was one person assigned to the school from the Sheriff's department: Neil Gardner.

Gardner was joined by motorcycle patrolman Paul Smoker, who had been writing a traffic ticket nearby.
By my definition, that is one armed guard at the school. Smoker was not in any way assigned to the school....
A 2015 study pitting the ~50 autonomous cars in California against the nationwide statistics for conventional cars found the accident rate of autonomous cars to be about five times that of the national average, with four times the injury rate.
However, the study also notes the very small statistical base -- there were just 11 accidents on file ...
Yes, and so much so that it can significantly affect accident rates.
A good study exploring this phenomenon is The mixed effects of precipitation on traffic crashes by Daniel Eisenberg.

Cherries are known to contain compounds are toxic in high enough dosages. But that ingredient is unlikely to be what caused this man's hospitalization.

Helium inhalation rarely causes negative effects in the long term, as the gas is inert and can't bond to haemoglobin within the blood (diffusional hypoxia - a common cause of illness after inhaling other gases).
Because, generally speaking, a person inhaling helium does so from a balloon, the loss of consciousness will usually result in the restore of the ...
Death rates for cause electric accidents (per million inhabitants and year) do not differ significantly between Ireland (UK type G) and Germany (Schuko), see below (I did not find similar statistics for the UK, nor sufficient detail to break the numbers down to plug/socket vs. other causes of electric accidents).
There are at least two safety ...
First of all, Google can find quite a lot of background on the dispute between Steve Lipsky and Range Resources Corp.

While aluminum is toxic in large quantities, the risks from intake of low quantities are uncertain. However, as a precaution it is recommended to minimize intake. For that reason acidic or salty food should not come into contact with uncoated aluminum, such as foils or dishes. Also, aluminum content of cosmetics should be minimized.
There is an ...
Yes helium can be dangerous, but usually because of other risky behaviour associated with taking it

Has anyone any got any statistics on the number of deaths and injuries from electrical plugs in Britain, and compared them to other areas that do not have these safety features in their power plugs?
Probably not, many have looked for such data without success.
