(a) On or before January 1, 2018, the department shall adopt regulations governing the specifications, installation, and use of child safety alert systems.

(2) A school pupil activity bus is not required to be equipped with an operational child safety alert system if all of the following apply:

The most commonly used end mills have either two or four flutes. Flutes are the deep helical grooves on the surface of the mill bit, responsible for channeling chips away from the workpiece.

(b) (1) (A) Except as provided in subparagraphs (B) and (C), on or before March 1, 2019, each schoolbus, school pupil activity bus, except school pupil activity buses described in paragraph (2), youth bus, and child care motor vehicle shall be equipped with an operational child safety alert system.

(F) After pupils have exited a school pupil activity bus, and before driving away, the driver shall check all areas of the bus, including, but not limited to, overhead compartments and bathrooms, to ensure that the bus is vacant.

They are commonly used in woodworking and metalworking applications to shape, contour, and create various features, such as slots, pockets, and holes. End mills are capable of cutting in multiple directions, making them versatile tools for achieving precise cuts and intricate designs.

(C) Any entity other than a school district, county office of education, charter school, or private school that operates a schoolbus, school pupil activity bus, except school pupil activity buses described in paragraph (2), youth bus, or child care motor vehicle that is subject to the requirements of this section may submit documentation as specified in subparagraph (B) to the department. Upon providing this documentation, the entity shall have an additional six months, not to extend beyond September 1, 2019, to meet the requirements of this section.

(E) Immediately before departure from any location, the adult chaperone shall account for each pupil on the list of pupils, verify the number of pupils to the driver, and sign a form indicating that all pupils are present or accounted for.

The rounded tip of the tool allows for smooth and gradual curves, making them ideal for 3D contouring, engraving, and sculpting operations. Ball nose end mills are particularly useful for creating complex shapes and contours, as they can reach into tight corners and create smooth transitions.

Carbide milling bits offer superior efficiency, speed range, and rigidity as compared to other end mill bit materials. While they tend to offer a comparable cutting edge, they’re capable of withstanding greater machining temperatures, making them ideal for even the most demanding workshop and factory environments.

They are ideal for use with metals and many other materials. This set includes 20 different sizes, so you can find the perfect mill for any job.

(C) One adult chaperone has a list of every pupil and adult chaperone, including a school employee, who is on the school pupil activity bus at the time of departure.

While the terms "mill" and "end mill" are often used interchangeably, it is important to understand their distinct characteristics.

(B) When the school pupil activity bus is used to transport pupils, the pupils are accompanied by at least one adult chaperone selected by a school official. If an adult chaperone is not a school employee, the chaperone shall meet the requirements for a school volunteer established by the policies of the school district, county office of education, charter school, or private school.

(2) “Child care provider” has the same meaning as provided for “day care center” in Section 1596.76 of the Health and Safety Code.

(1) “Child care motor vehicle” means a vehicle designed, used, or maintained for more than eight persons, including the driver, that is used by a child care provider to transport children.

(d) A “child safety alert system” is a device located at the interior rear of a vehicle that requires the driver to either manually contact or scan the device before exiting the vehicle, thereby prompting the driver to inspect the entirety of the interior of the vehicle before exiting.

Two-flute end mills are ideal for general-purpose milling tasks, providing good chip evacuation and stability. On the other hand, four-flute end mills offer increased tool strength and higher feed rates, making them suitable for heavy-duty operations and materials that tend to work harden.

(D) The driver has reviewed all safety and emergency procedures before the initial departure and the driver and adult chaperone have signed a form with the time and date acknowledging that the safety plan and procedures were reviewed.

End mill bits are used for cutting laterally across a workpiece with equipment like drill presses, routers, and CNC (Computer Numerical Control) machines. Whereas drill bits cut through a material (and are moved up and down), milling bits are moved from side-to-side for pocketing, engraving, contouring, and other similar processes.
